can't start container... error starting userland proxy: listen udp4 1900 bind address already in use...

all of sudden, the jellyfin container stopped. i restarted and killed and restarted the jellyfin container.. but still got Failure

there is something using the same port. so i checked

root@openmediavault:~# netstat -pna | grep 1900

unix 3 [ ] STREAM CONNECTED 51900 534/dbus-daemon /var/run/dbus/system_bus_socket

and i cecked all the containers but there is no container using port 1900 except for jellyfin...

i don't know what to do..

thank you in advance.

there is no container using 1900..

i killed 31569

it's weird. keeps occuring.

so

i just removed the port option - 1900:1900/udp in jellygin stack. and updated the stack. it worked.
