You said you got a valid cert from LE, but are you using a reverse proxy or are you using Jellyfin's built in https server? Since you are using port 8920, I am assuming you are using the built in https functionality (not recommended).
Did the installed cert expire? LE certs are only valid for 90 days. And Jellyfin does not have an auto-update mechanism.
