Noob question, how to access Jellyfin installed on Synology container manager?

[tmsrxzar]

So when I try to access "https://localhost::8096" i just get Unable to connect. Firefox can’t establish a connection to the server at localhost:8096

unless you are using firefox on the NAS itself (unlikely), localhost is never going to work - that connects back to the machine you're on

try the ip of the NAS instead
