This is a small excerpt of messages I receive in the log. Should I worry? I’m asking because in my mind there shouldn’t be such messages in that short time frame?!

My server is behind a reverse proxy if that matters.

Thanks!

2

Which Linux distro and version is this?

Would it be possible to get the full DEBUG logs ZIP file ?

I do suspect there’s a proxy problem.

3

It’s running in docker within unraid.

Check PM

Thank you! :slight_smile:

I have sent you a PM.
My PMs are not open

Do the logs you’re sending me have the websocket messages in them or are you seeing system messages?
