Did you try restarting electrum and then connecting to a different server if it didn't work just by restarting?
Why do you say you downloaded from electrum.org using the link in the wallet? What wallet did you update from?
I don't know anything about connecting to a different server. I did restart.
I'm not sure what you're asking (What wallet did you update from?) I had 3.3.8 Windows Installer version downloaded. I clicked on the upgrade available link at the bottom of the screen when I opened the wallet.
