  1. Are you using official Traccar server? And which version?
  2. What's in your configuration file?
Bhanu From Nepal last year

I am using Traccar Version 6.5 on my own VPS.
My configuration for firebase of traccar.xml is :

And you're using the same Firebase project for your app? The error seems to indicate that it's not the case.

Bhanu From Nepal last year

I am using same project on app too. And from Announcement menu from admin dashboard when I am trying send message to specific user it works fine. But Notifciation not goes on ignation on or off , command result etc.

Anton Tananaev last year

Are you sure all the users are/were using the same app?

Bhanu From Nepal last year

Yes!

Anton Tananaev last year

Well, the error seems to indicate otherwise.
