Are you using official version of the app?

Yes, download source code and build.

Then it won't work obviously. Your signatures won't match the official app. Are you also using our Firebase config?

Ah... of course then!
It was not clear from the documentation that there was this requirement to use the traccar domain.

I will download it through the playstore and use the official app.

Thanks for the feedback.
