It seems that there is something blocking your Electrum to connect in any Electrum server.
Are you using a VPN? Try to disable it and try again. If not, then try to change your PC/Laptop DNS.
You can choose any of these DNS below.
- 8.8.8.8 and 8.8.4.4 = Google DNS
- 1.1.1.1 and 1.0.0.1 = Cloudflare DNS
After you manually set the DNS, follow this.
- Open CMD
- Type "ipconfig /release" then enter
- Type "ipconfig /renew" then enter
- Type "ipconfig /flushdns" then enter
Then try to check your Electrum again if the circle turns to green.
It is so only on this wallet, so I shot a video where everything is ok, but it is worth opening this wallet and the one that was opened also loses the network
