401 with Firefox 83.0

[sysoppl]

Hello,
I just deployed my docker container, and with some research I was able to sync with my Android phone ( https://example.com/token/ ), however I'm unable to sync with my firefox desktop (83.0).

Docker logs says:
INFO:mozsvc.metrics:{"code": 401, "request_time": 0.00031304359436035156, "remoteAddressChain": ["1.2.3.4", "172.17.0.1"], "agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0", "path": "https://example.com/token/1.0/sync/1.5", "method": "GET"}

Also, there was crash or something inside, here is the log:
sync_logs.txt - I removed some ip's and url's

I tried with
http://example.com/token/1.0/sync/1.5
http://example.com/token/token/1.0/sync/1.5
http://example.com/token/

After setting these two to false and few relogins I was finally able to sync...

After setting these two to false

Just want to let you know, those prefs will eventually be removed from Firefox, so we can't count on them for a long-term solution here.

When you have a chance, please try setting those prefs back to False, reproducing the 401 error, and then following these instructions to capture more detailed client-side logs about what might be going wrong?

Well, I set them back to true, but no 401 in logs for now..
I will try with fresh firefox or it will pop 401 soon, I'll see in few days

Those settings do not exists in Firefox for Android since last august. Probably reason, why I cannot get sync to work even with https.

@virgoparna For Android version I'm using https://URL/token/ without changing any settings and it is working fine

Got Android version to sync by new install. Old sync server was probably too old.

So you did this with the current server which source is available here? w/o adding any SSL certs or whatsoever? You even did not change the URI to https://URL/token/1.0/sync/1.5 with or without trailing slash?

I'm using 3 months old version with Lets Encrypt SSL. It is just https://URL/token/ without any /1.0/sync etc.
