[Question] How to check if browser actually syncs with my server? about docker-firefox-syncserver

[doc75]

@zilexa , have you tried in your firefox to check the about:sync-log content ?
I have also a sync issue and can see error in the logs (but I do not know how to solve them 😟 )

I was using Firefox Beta for Android. I installed Firefox for Android besides it and changed the url (after tapping the logo in About Firefox 5 times, this option becomes visible in Settings).

Unfortunately, after authentication, "last sync" stays on Never (Firefox for Android). Even if I tap to sync.

It seems now, both my desktop Firefox and my (new) Firefox for Android are not syncing.
With my old Firefox Beta for Android, I logged out of Sync, changed the URL. Now after a login attempt (authentication), the Firefox Beta app itself is still not logged in. I am logged in on the website and shown as Web Session when I go to my account page. But the Firefox Beta app is not logged in.

Something seems to be going wrong here.

What could have gone wrong here?
The Traefik setup works fine, I use it for multiple services and in Traefik webUI I can see all is OK.

Enabled debug logging:

2020-10-21 17:10:57 +0000] [17] [DEBUG] GET /token/1.0/sync/1.5
ERROR:syncserver:The public_url setting doesn't match the application url.
This will almost certainly cause authentication failures!
    public_url setting is: https://firefox.obelix.cloud
    application url is:    http://firefox.obelix.cloud
You can disable this check by setting the force_wsgi_environ
option in your config file, but do so at your own risk.

this does not make sense as I state https:// in Compose and also in the url on my devices. If I disable the check via the env the error goes away. But the issue remains.

Thanks I will try tomorrow. Had some other unrelated stuff to fix first.
Do post your error please, I'll check my log tomorrow.

The issue remains with application url is: http://firefox.obelix.cloud
While it is https. How can I change the application url ?

I have got it working. Not sure how or why.

Did not chang any Traefik label.
Note on Android I accidentally changed the Auth server. Be careful to select sync server.
You will get both options via Firefox > Settings > About > tap the logo 5 times > go back to Settings > see the extra options under Sync > Only change the sync server to https://firefox.yourdomain.com/token/token/1.0/sync/1.5

You can also test in a browser:
https://firefox.yourdomain.com/token/
should not show any errors.

BUT: nothing gets synced. I will open a new issue.
