It is also possible that the firewall and internet rules of your workplace network are setup in such a way that Electrum is not able to work correctly due to ports being closed and/or certain domains being blocked etc.

Definitely, let's check:
- Go to console and get the server name you are trying to connect. For example: elec.luggs.co:443
- Resolve the IP address: ping elec.luggs.co (Windows) or host elec.luggs.co (Linux)
- elec.luggs.co has address 95.211.185.14
- Check if your PC connected to this server:
. netstat -an | findstr 95.211.185.14 (Windows)
. netstat -an | grep 95.211.185.14 (Linux)
- If you are connected, you should see something like:
tcp 0 0 192.168.x.y:zzzz 95.211.185.14:443 ESTABLISHED

Instead of ESTABLISHED, you may have SYN_SENT which mean your PC is trying to reach the server but failed probably because something is blocking your request: your firewall or any antivirus. Therefore, you need to permit this outgoing flow from your programs.

I am pretty sure you are using Windows and the Defender prevents Electrum to reach your server.
