Emby client breaks Emby Server connection

[Guest]

Emby client started a conversion process and I noticed it and stopped the process on the server-side. Now, the client's device tries polling the server on the conversion/sync progress and it appears to make Emby refuse all connections from that source (from my nginx proxy, so basically any connections through my duckdns.org domain) and results in a 502 error.

My setup is:

Router port forward ports 80, 443 --> nginx-proxy-manager hosted on docker on my Ubuntu (192.168.1.13), which routes to my Emby Server on Docker

Nginx logs attached, Emby Server logs attached as well.

Hello b074f3ba,

** This is an auto reply **

Please wait for someone from staff support or our members to reply to you.

It's recommended to provide more info, as it explain in this thread:

Thank you.

Just a guess, some server or connection has flagged this traffic as inappropriate and is refusing further connections.  it may clear when a timeout period is reached.  Perhaps security backend firewall setting picks up failed packet traffic and blocks it...  maybe even your host.  Search for failed connection traffic blocked security and your OS info.

Hope that helps.

New logs with close timestamps. Emby has a `Error SessionManager: Error sending message` in the logs several times. Not sure if it is causing my issue or not, but seems interesting.

@b074f3ba I would suggest comparing your nginx config to that of @pir8radio:

Please let us know if this helps. Thanks.

[Guest]

I think I have have fixed my problem. I routed the connections directly to the docker0 network on 172.17.0.1:8096 and let that route to my Emby Server instead of going through the local LAN IP address of 192.168.1.13:8096. Haven't had it error out since.

Thanks for the feedback.
