Previously saved Spotify login details fail to login after restarting Kodi 19.3 using LibreElec 10

[TylerDurden2019]

I'm using LibreElec 10 with Kodi 19.3 on a RPi400.
After installing the ldsz spotify add on and adding my premium account details it connects and I can play music. But if I restart LibreElec/Kodi when it starts up there is a login error with the Spotify account and I can't relogin unless I remove or re enter my Spotify credentials multiple times.
Has anyone else encountered this issue? Any tips?

Same for me with coreelec, i.tried the buffer set to 0 with no change, always complaining about credentials..

Same for me, using on CoreELEC 19.4 always getting error below.

Same credential (premium) works on IOS or WINDOWS for 100%, checked the spelling several times
Adding buffer to 0 or 1 as proposed link does not help either

Network related (firewall issue) ? seems that system tries to create webproxy on 52308 port
