You’re most likely to find something about what’s going on in web.log, but 42k lines of debug logging is a bit much to get through. Instead, can you tail -f web.log and watch what happens while you’re trying to log in, and capture & forward that logging?
this is the line that appears (4 times) when I try to login:
2022.09.12 16:10:01 DEBUG web[AYMyCG0DoT635v0OAAAK][auth.event] login failure [cause|User must be authenticated][method|BASIC][provider|LOCAL|local][IP|0:0:0:0:0:0:0:1|192.168.0.254:59956][login|]
The logs I sent before were in TRACE mode. Let me know if you need them in DEBUG or only in INFO.
