Installed it through ubuntu PPA and now everything just works!

@jonas Oh sorry. Missed that. And I see there's an ubuntu ppa. great!

I just found out that Strawberry existed and that made me very happy!
There is one problem with my version when it comes to scrobbling. I am running Strawberry-0.9.3-Qt6-x86_64.AppImage on my KDE neon installation that now is based on ubuntu 22.04 because the .deb could not be installed for some reason.

When I press Login, get the URL, paste in firefox, logged in to last.fm and clicks Allow then it jump back to Strawberry but with an error saying "Authentication failed" with subtext "Host ws.audioscrobbler.com not found (3)".

I am running it from the terminal and nothing new comes up when I do this Login-process, so there is no debug output to show.

When playing a song I see errors like

19:46:14.283 ERROR AuddLyricsProvider:189           AudDLyrics: "Host api.audd.io not found (3)"
19:46:14.283 ERROR OVHLyricsProvider:121            OVHLyrics: "Host api.lyrics.ovh not found (3)"
19:46:14.283 ERROR LoloLyricsProvider:159           LoloLyrics: "Host api.lololyrics.com not found (3)"
19:46:14.283 ERROR MusixmatchLyricsProvider:220     MusixmatchLyrics: "Host www.musixmatch.com not found (3)"

but I do not need lyrics so that is alright... but just the host not found errors are similar. Something that also sounds similar is:

Any idea what it could be?
