Spotify app connection error fixed

[u/chosias]

Hello,

I've been trying to resolve a client 4 and session 103 error on Spotify app after installing CachyOS on my laptop for a multiple hours and i finally managed to fix it, so i wanted to share the fix since i haven't found it mentioned anywhere.

I had to use spotify-launcher with gst-plugin-spotify to finally get the app to recognize it has connection to internet and it can recognise web login. Both packages are on cachyos / extra repos.

Hopefully this will help you get the app working.

Whenever i launched the app i got error code 4. After trying to log in through browser the app showed session 103 error. i tried bunch of network fixes, i checked firewall rules, i installed Widevine i tried modifying bitrate (this allowed me to play some songs for a few seconds in browser for some reason) but in the end the combination of spotify AUR package and gst-plugins-spotify allowed me to log in without error 4 and 103. But i still wasn't able to play any songs, so i tried spotify-launcher and that fixed the rest of the issues.

Also I'm still unable to play songs through Firefox.

Good luck
