Reconnecting issue

There are few days now since I can't use Lichess in my laptop's browser. No game is starting and I can't even move in puzzles. I tried several different networks, all of them with strong internet connections, but I still get that red reconnecting pop up in the left corner.

Mention that the mobile app is working fine and the phone is connected to the same network as my laptop.

Any idea about how to solve this?

Thanks,
Dragos
