Freezing lovelace on edge and Chrome

Configuration Frontend
1

Since a couple of days my main lovelace UI is freezing in edge and chrome! When I open the main page in Firefox there is no problem at all. Also If I open it on a different PC (laptop) there is no problem.

It seems related to only one PC (desktop) sofar.

Any idea what can cause this?

I do have the same issues, as of today also on Edge doesn’t want to load the “dashboard” login works. I 've got the idea it has to do with how i login (duckdns - certificate). Who can help me/us?
