Desktop client permanently loosing connectivity

[kng]

Steps to reproduce

After several months of use app suddenly stops working and all attempts to clean up fails.
It started with this error message:

Then after removing %AppData%\Element and %LOCALAPPDATA%\element-desktop and reinstalling from here it never gets past the "homeserver misconfigured" screen.
Sorry for local language, but it's automatically selected.

I have been searching for the logs but not finding any in the above mentioned directories nor the windows logs.
Tried to start from command line and got this:

C:\Users\user\AppData\Local\element-desktop\app-1.11.16>Element.exe
C:\Users\user\AppData\Roaming\Element exists: yes
C:\Users\user\AppData\Roaming\Riot exists: no

I had another go at this, looked in windows certificate browser. Discovered at least one "personal certificate" that had recently expired. But I didn't pay any attention to it earlier because of the lack of info in it matching riot/matrix/element. But deleting it solved at least the nightly client. Unfortunately I didn't copy/screendump it before removing it. It had something like "Token" in the info.

I just ran the Element Setup.exe recently downloaded. Now the nightly is broken again with the "connectivity to the server has been lost". Can someone explain this ? The installers are super silent and no confirmations or questions.
