The problem

SInce a couple of days ago, I've been getting this issue in my logs. I've tried logging in to Plex and Trakt again but that hasn't resolved the issue. I run the app in Docker with command 'watch'.

I also run a cronjob to execute sync as a separate command every 15 minutes and that is working fine.

This is some kind of networking error in your network or docker. Nothing we can do. Especially as no software was updated in the process. You might try restarting docker daemon or rebooting the host.

You may also check logs of your Plex Media Server, maybe anything useful there.

Thanks for your answer. I updated my router software recently and it broke local DNS - I had to add some settings in the router to reinstate that. Also, my Docker Subnet changed from 172.16.0.0 to 172.17.0.0, so I had to create a new Route to my LAN.

Anyway it's working fine again now. Sorry to disturb !

In case anybody comes across this issue, I figured it out eventually. I edited servers.yml and made sure the urls entry listed there match my docker environment variable PLEX_ADVERTISE_URL and also the 'Custom server access URL' in Plex Network Settings.

Also, test that URL (try to open it) so if you use https it doesn't give certificate errors. If the log shows that AlertListener is using 'wss', it means you specified 'https'. If using 'ws', it means you specified 'http'.

In Plex Network Settings set Secure Connections to 'Preferred' not 'Required'.

Once all the above was set I got 'Websocket connected'
