I have a problem since several days, Electrum showing the red icon in the lower right and doesn't want to connect to any server.

Running 3.3.8 since it came out in July. Back then it worked fine and nothing on my laptop config has changed since then.

What I've tried so far:
- tried all different electrum versions (portable, installer etc.), same result for each
- whitelisted in firewall
- deleted the file blockchain_headers
- tried to manually connect to the servers that are available inside the software, as well as those listed at https://1209k.com/bitcoin-eye/ele.php
- have been waiting a good 10 mins between trying new servers
- above issues are both for NO proxy and with proxy

It feels like I tried everything there is to try. It doesn't make sense that 3.3.8 would work fine for me a few weeks ago and now it doesn't since days.

Any other ideas?
