No matter what I try by docker synology instance of Seerr retrieves the server list no issue but then only give me option for manual configuration and every drop down option is grayed out. Every address and port and web app url I still get failed to connect to plex server.

plex network is 192.168.1.62:32400
seerr is 192.168.1.62:5055 and also 172.20.0.4 on the docker bridge network.

all other containers on docker like sonarr and radarr are accessible via 192.168.1.x subnet

Okay so

#

Do this

#

docker exec -it -u 0 seerr sh

#

Then apk update && apk add curl

#

Then curl -L http://192.168.1.52:32400

Turns out all I needed to to was use the 172.20.0.1

Thanks for the help
