failed to bind port - primordialrage - 2025-07-12
Greetings
I wanted to reach out to the community and see if anyone has had this issue, if not maybe if there is any information on how I can dig deeper in finding the root cause of this issue, or if there is any additional data or information needed
############
Problem statement
############
In portainer I changed the docker compose stack in order to bind some more media directories, and when I ran the compose it generated the following:
"curl: (7) Failed to connect to localhost port 8096 after 0 ms: Couldn't connect to server"

Workaround
#########
completely remove all data/folders associated with current jellyfin and then rebuild jellyfin with new folders/data (not able to use previous config/data)
this has happened 3 times and in one instance I also had to rename the new config and cache folder to ncache and nconfig (see compose below) and make the appropriate changes in the docker compose.
I also made a copy of the compose onto the device and ran it to rule out issue with portainer but port binding issue remained
I can recreate the issue by trying to run new instance of jellyfin with old files
