Can't start Jellyfin - ACTransitBusFightIAAMF - 2025-05-01
I've downloaded Jellyfin onto a Windows machine.
I installed it, I start it, a load of text flashes up and speeds by, then nothing happens.
I've gone into the folder and clicked the Jellyfin thing again, same thing happens. Tried running as Administrator, same thing happens.
I'm able to start up the Jellyfin Windows Tray app, but when I double click it I get a "This site can't be reached" error.
Quote:localhost refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
I did have a previous installation of Plex, I've uninstalled that now and it hasn't done any good.
I fully uninstalled Jellyfin (i.e. deleted all data) and reinstalled it, same problems.
I don't think it's an issue with the cache of my browser or anything like that, since I've opened it in incognito tabs and browsers I've never used Plex with and had the same issue.
This is the log I get

RE: Can't start Jellyfin - theguymadmax - 2025-05-01
You need to remove 'C:\Program Files\ffmpeg-2023-10-16-git-5ddab49d48-full_build\bin' from your system environment variable:
In the start menu or a run box type “sysdm.cpl” and open that up.
Navigate to Advanced -> Environment Variables
In User Variables - click Path, then choose edit. Check for a ffmpeg path and delete if found.
Do the same thing for the System Variables.
Restart your computer.

I got rid of the ffmpeg from my environment variables and I've seen progress of a sort. Now when I click the tray icon I get a big splash screen saying Jellyfish but nothing else happens.
I'm not sure what the other System Variables you're referring to are. Do I just clear out all of the Environment Variables in the System Properties?
Edit: Never mind, turned out that was a Chrome issue, there's an extension I have that blocks HTML5 playing. Disabling the extension for that page and/or using a different browser works great. Thanks!
