Sorry, I thought I had published v4 of the plugin. Please update to that and try again. Should be available in 15-20 minutes.

[rainer-geiger]

Tested again and the new version isn't available until now. I'll just wait a little longer, but I wanted to let you know in case there are other reasons.

If you need it right now, you can also download the latest build artifact. Just extract the archive into plugins/DLNA_3.0.0.0, replacing all files.

Thank you very much! I was already thinking about downgrading Jellyfin - or looking for a HDMI cable for my projector.

[Nullcaller]

No worries. Report back if you have any problems.

[Nullcaller]

Ah. I know what the issue is. The version somehow didn't get changed to 4.0.0.0. If you look at the release, there's an archive with the plugin, but it's called "dlna_3.0.0.0.zip". And in fact, if you download version 3.0.0.0 from the repo, you'll discover that it's the same zip. So, in theory, if you just delete the plugin from Jellyfin and then reinstall it (remember to back up your setttings and profiles though), you'll install 4.0.0.0, it's just gonna look like 3.0.0.0.

[rainer-geiger]

I had already reinstalled the plugin without success before I created the issue. I also noticed that the build artifact is still on version 3, I copied the files manually for now and it works just fine :)

[Nullcaller]

Nice! Glad you were able to fix it :)

Weird reinstalling didn't work, though. Maybe the release used the old zip...

[rainer-geiger]

I probably should have restarted Jellyfin after uninstalling it because nothing had changed in the files after the reinstallation. But I learned something new about Jellyfin today and thanks again for the kind support!
