SOLVED: Can't connect to server

[TheDreadPirate]

You're using http://192.168.178.33:8096 in your browser? If you are on the same machine running Jellyfin http://localhost:8096 will also work, and bypasses the firewall.

Can you disable the Windows firewall entirely? I've seen cases, including personally, where Windows firewall just straight up breaks after an update. Any rules in Windows firewall aren't actually applied and honored. I had to disable Windows firewall entirely and so did another user here on the forum.
