3CX Push Failure, All Ports are Open, "UnAuthorized" Error

[Nanogeek]

Good Morning,

This problem has given me quite a bit of headache, because I can't for the life of me figure out the problem.

Push is ENABLED in the extension. The following ports are open:

3CX-HTTP 80 TCP
3CX-HTTPS 443 TCP
3CX-SIP Protocol 5060 BOTH
3CX-Tunnel Protocol 5090 BOTH
3CX-Media Server (RTP) 9000:9255 UDP
3CX-External Media Tr... 9256:9500 UDP
3CX-PUSH 5228:5230 TCP

If I have the phone unlocked, and 3CX open on the screen. It receives the call. If I switch to a different page (phone unlocked) 3CX is in the header and says "Push Enabled - Ready for Calls" but does not ring what so ever. This behavior occurs both on 4g and Wireless.

I've also attempted (Very quickly) to turn off the firewall at the server and router. No change.

I went into the logs, and looked at 3xcDialer. I noticed this particular snippet:

16/03/29 09:08:24.010|200001| Err|10|0017|: *!* Exception catched at Android Push sender:
System.Net.WebException: The remote server returned an error: (401) Unauthorized.
   at System.Net.HttpWebRequest.GetResponse()
   at Dialer.PushClient.PushAndroid(CallData c, Int32 reason)
16/03/29 09:08:24.419|200001| Err|10|0014|: *!* Exception catched at Android Push sender:
System.Net.WebException: The remote server returned an error: (401) Unauthorized.
   at System.Net.HttpWebRequest.GetResponse()
   at Dialer.PushClient.PushAndroid(CallData c, Int32 reason)

This seems really strange that it says not authorized. For what its worth, I went in and deleted the PUSH project from Google, re-created, resent provision e-mail to the phone, and it still didn't work. Even re-installed 3CX App on the phone.

Any ideas? I'm sure I'm missing something simple here...

The log would seem indicate an incorrect entry somewhere. Did you have 3CX create a new provisioning file (after changing the Google Push account) before sending (again) to the phone?
You can review the file, if it is sent to a regular email account as well, by opening with notepad. Have a look at the GCMSENDERID, that should be the project ID

 

[Nanogeek]

Just reviewed the provisioning file, and it does indeed match the current project number. But yes, I did send a new provisioning file.

The bad thing is, I've setup another 3CX system about 2 months ago, using roughly the same hardware, and never had an issue. This one has be stumped.

In the Management Console, in the PUSH settings is the Project Number alphanumerical or only numerical? In the Google Developer Console you see the whole Project ID however the Project Number is only the last part of the ID as highlighted bellow.

NickD,

It's only numerical. I went to the front of the dashboard to actually get the number (Where it lists only the project number).

I'm still stumped on this. Does anyone need more logs?

 

[Nanogeek]

Also,

The numbers at the end of the project ID are different than the Project Number. (Project number is much longer, but still numerical). I was under the impression that 3CX needed the Number, not ID. That's how I configured it the first time a couple months ago, and it worked fine.

FWIW, I tried replacing Project Number with the last numerical digits in Project ID, but no go. Still says failure.

 

[Nanogeek]

Whelp,

I fixed it. Wish I could say it was a satisfactory fix, but nope. Seems as if it was a bug. I had previously hosted a project on this developer account, so my Google Cloud Messaging API was already enabled. I decided to simply disable and then re-enable it, on a whim.

BOOM. Everything fricken works as it should now. No fricken clue why. God bless Google.....

Same issue here but unfortunately not the same way to resolution.

Anyone got a clue how to troubleshoot this? 3CX PBX v14 SP 3.

Looks like you are receiving an unauthorised error back from google. In that case you should re-create your push project and once that is done you need to send new welcome emails to your mobile clients.
