Notification server fails

Hi
I followed instructions and set up notification server as I dont suppose push-test.mattermost.com works for push notifications to Android.
When testing with curl, I get this error:
{“error”:“mismatched sender id”,“status”:“FAIL”}

I assume I shoul dprovide sender_id as serverID from google, but I dont know where to supply this information.

Any ideas

Hello, @ga5tan

I would like to understand this part a little better:

Is the Mattermost Server that you are running on has a firewall that blocks connection to the default https://push.mattermost.com (US) and https://hpns-de.mattermost.com/ (Germany) listed in the documentation?

Can you also share the documentation / article you referred to when setting up the notification server you mentioned? Also, can you also provide the full cURL command you used for testing?

Well I’ll be damned. I think we unfirewalled push-test.mattermost.com and now it works with your server.
So that’s a good news. But since you advertise your test server may not be stable enough, I would like to make hosted push working.
This is the documentation I followed:
https://developers.mattermost.com/contribute/mobile/push-notifications/service/

and it seems to be working (curl test) to the point, where push server talks to google services/api
but google does not like all the info supplied.
