Unable to connect to live ‘ssl://gateway.push.apple.com:2195’

I am facing issue with APNS php code for push notification on IOS devices, I have two separate connection for Development and Production.

  1. I have configure the development connection on my server by adding the .pem file certificate and Passphares its working perfect and I received the notification also. Have a look my development configuration:

Url: ‘ssl://gateway.sandbox.push.apple.com:2195’

Issue:

  1. Than I configured the connection for Production by adding following parameters but I getting the connection error:

Url: ssl://gateway.push.apple.com:2195

Error of connection: INFO: Trying ssl://gateway.push.apple.com:2195. ERROR: Unable to connect to ‘ssl://gateway.push.apple.com:2195’: (0) INFO: Retry to connect (1/3). INFO: Trying ssl://gateway.push.apple.com:2195. ERROR: Unable to connect to ‘ssl://gateway.push.apple.com:2195’: (0) INFO: Retry to connect (2/3). INFO: Trying ssl://gateway.push.apple.com:2195. ERROR: Unable to connect to ‘ssl://gateway.push.apple.com:2195’: (0) INFO: Retry to connect (3/3). INFO: Trying ssl://gateway.push.apple.com:2195. ERROR: Unable to connect to ‘ssl://gateway.push.apple.com:2195’: (0)

I google the issue and I found the some solutions and I have check all and everything is fine but no success.

  • I have used the correct path for development and production.
  • I have created the separate certificate .pem files for both and tested the certificate on pusher app. Certificate are correct.
  • Port is also fine and no blocking from my server because same port is used in development url and development server push notification working fine.

Any help will be appreciated really. Thanks in advance.

Local and Remote Notification Programming Guide

Binary Provider API

The legacy binary interface required your provider server to employ the binary API described in this appendix. All developers should migrate their remote notification provider servers to the more capable and more efficient HTTP/2-based API described in Communicating with APNs .

General Provider Requirements

As a provider, you can communicate with Apple Push Notification service over a binary interface. This interface is a high-speed, high-capacity interface for providers; it uses a streaming TCP socket design in conjunction with binary content. The binary interface is asynchronous. The interface is supported, but you should prefer the use of the modern APNs API if possible.

The binary interface of the production environment is available through gateway.push.apple.com , port 2195; the binary interface of the development environment is available through gateway.sandbox.push.apple.com , port 2195.

For each interface, use TLS (or SSL) to establish a secured communications channel. The SSL certificate required for these connections is obtained from your developer account. (See APNs Overview for details.) To establish a trusted provider identity, present this certificate to APNs at connection time using peer-to-peer authentication.

To establish a TLS session with APNs, an Entrust Secure CA root certificate must be installed on the provider’s server. If the server is running macOS, this root certificate is already in the keychain. On other systems, the certificate might not be available. You can download this certificate from the Entrust SSL Certificates website.

As a provider, you are responsible for the following aspects of remote notifications:

You must compose the notification payload (see Creating the Remote Notification Payload ).

You are responsible for supplying the badge number to be displayed on the app icon.

Connect regularly with the feedback service and fetch the current list of those devices that have repeatedly reported failed-delivery attempts. Then stop sending notifications to the devices associated with those apps. See The Feedback Service for more information.

If you intend to support notification messages in multiple languages, but do not use the loc-key and loc-args properties of the aps payload dictionary for client-side fetching of localized alert strings, you need to localize the text of alert messages on the server side. To do this, you need to find out the current language preference from the client app. Supplying the User’s Language Preference to Your Server suggests an approach for obtaining this information. See Creating the Remote Notification Payload for information about the loc-key and loc-args properties.

The Binary Interface and Notification Format

The binary interface employs a plain TCP socket for binary content that is streaming in nature. For optimum performance, batch multiple notifications in a single transmission over the interface, either explicitly or using a TCP/IP Nagle algorithm. The format of notifications is shown in Figure A-1 .

Figure A-1Notification format

All data is specified in network order, that is big endian.

The top level of the notification format is made up of the following, in order:

Table A-1Top-level fields for remote notifications

Populate with the number 2 .

The size of the frame data.

The frame contains the body, structured as a series of items.

The frame data is made up of a series of items. Each item is made up of the following, in order:

Table A-2Fields for remote notification frames

The item identifier, as listed in Table A-3 . For example, the item identifier of the payload is 2 .

Item data length

The size of the item data.

The value for the item.

The items and their identifiers are as follows:

Table A-3Item identifiers for remote notifications

Up to 100 bytes

The device token in binary form, as was registered by the device.

A remote notification must have exactly one device token.

Variable length, less than or equal to 2 kilobytes

The JSON-formatted payload. A remote notification must have exactly one payload.

The payload must not be null-terminated.

An arbitrary, opaque value that identifies this notification. This identifier is used for reporting errors to your server.

Although this item is not required, you should include it to allow APNs to restart the sending of notifications upon encountering an error.

A UNIX epoch date expressed in seconds (UTC) that identifies when the notification is no longer valid and can be discarded.

If this value is non-zero, APNs stores the notification tries to deliver the notification at least once. Specify zero to indicate that the notification expires immediately and that APNs should not store the notification at all.

The notification’s priority. Provide one of the following values:

10 The push message is sent immediately.

The remote notification must trigger an alert, sound, or badge on the device. It is an error to use this priority for a push that contains only the content-available key.

5 The push message is sent at a time that conserves power on the device receiving it.

Notifications with this priority might be grouped and delivered in bursts. They are throttled, and in some cases are not delivered.

If you send a notification that is accepted by APNs, nothing is returned.

If you send a notification that is malformed or otherwise unintelligible, APNs returns an error-response packet and closes the connection. Any notifications that you sent after the malformed notification using the same connection are discarded, and must be resent. Figure A-2 shows the format of the error-response packet.

Figure A-2Format of error-response packet

The packet has a command value of 8 followed by a one-byte status code and the notification identifier of the malformed notification. Table A-4 lists the possible status codes and their meanings.

Table A-4Codes in error-response packet

No errors encountered

Missing device token

Invalid token size

Invalid topic size

Invalid payload size

Protocol error (APNs could not parse the notification)

A status code of 10 indicates that the APNs server closed the connection (for example, to perform maintenance). The notification identifier in the error response indicates the last notification that was successfully sent. Any notifications you sent after it have been discarded and must be resent. When you receive this status code, stop using this connection and open a new connection.

Take note that the device token in the production environment and the device token in the development environment are not the same value.

The Feedback Service

The Apple Push Notification service includes a feedback service to give you information about failed remote notifications. When a remote notification cannot be delivered because the intended app does not exist on the device, the feedback service adds that device’s token to its list. Remote notifications that expire before being delivered are not considered a failed delivery and don’t impact the feedback service. By using this information to stop sending remote notifications that will fail to be delivered, you reduce unnecessary message overhead and improve overall system performance.

Query the feedback service daily to get the list of device tokens. Use the timestamp to verify that the device tokens haven’t been reregistered since the feedback entry was generated. For each device that has not been reregistered, stop sending notifications. APNs monitors providers for their diligence in checking the feedback service and refraining from sending remote notifications to nonexistent apps on devices.

The feedback service maintains a separate list for each push topic. If you have multiple apps, you must connect to the feedback service once for each app, using the corresponding certificate, in order to receive all feedback.

The feedback service has a binary interface similar to the interface used for sending remote notifications. You access the production feedback service via feedback.push.apple.com on port 2196 and the development feedback service via feedback.sandbox.push.apple.com on port 2196. As with the binary interface for remote notifications, use TLS (or SSL) to establish a secured communications channel. You use the same SSL certificate for connecting to the feedback service as you use for sending notifications. To establish a trusted provider identity, present this certificate to APNs at connection time using peer-to-peer authentication.

Once you are connected, transmission begins immediately; you do not need to send any command to APNs. Read the stream from the feedback service until there is no more data to read. The received data is in tuples with the following format:

Figure A-3Binary format of a feedback tuple

A timestamp (as a four-byte time_t value) indicating when APNs determined that the app no longer exists on the device. This value, which is in network order, represents the seconds since 12:00 midnight on January 1, 1970 UTC.

The length of the device token as a two-byte integer value in network order.

The device token in binary format.

The feedback service’s list is cleared after you read it. Each time you connect to the feedback service, the information it returns lists only the failures that have happened since you last connected.

Unable to connect to ‘ssl://gateway.sandbox.push.apple.com:2195’

I sucessfully run the APNS code in my macbook air, but it turns out that I can not run it in my other computer:

I checked that these are the same: 1. .pem file ( to be specific ) 2. Program

The computers can not work are:

Windows 7,XAMPP,OpenSSL supported,No firewall

EC2 Linux server with 2195 and 2196 opened

What might be other issues causing that I got this error in my php code?

I know there might be cause by not opening SSL, but I checked the phpInfo(), it should be correct.

I tried telnet in EC2 server, it gives:

That’s it..hope this may help further seekers.

Unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Connection refused)

I have a problem, I’d like to send out push notifications using php, however I keep getting this error:

My code is as follows:

I believe the problem is with the server I’m using because I posted the same code and the same .pem file on a different server and it sent the notification without any problem. I attempted to open up ports on the firewall for my server because I read that might cause this problem, but the same error message still showed up. Is there anything else I can do? Any help would be greatly appreciated, thanks!

This issue is common problem in Apple Push notification, to resolve this error you have to go through as follows:

Test your pem files locally and remotely in server if the problem is server go to 2 else build pem correct file.

Set up the permission wrong on the folder that had the certificate file. This worked for me:

chmod 755 your_folder_that_has_certificate_files

3.Check connectivity of apns port 2195 from your hosting server as follows:

if this is the problem

you can solve this issue by opening the port 2195 on the production server. You can verify by following command $telnet gateway.push.apple.com 2195

username/foldername/filename hit thats it
