Yeah I know I have last ver but I just want to know why i get update failed? When I was click (before) on check for updates I get message > you have last update.
I just use VPN not tor and I yea i have 3.3.8 ver
It might be because of your VPN that is why you are getting update fail/error.
How about trying to disable the VPN to test it might be blocking your Electrum from requesting on Electrum server that is why you are getting update failed. So disabling VPN might solve your issue.
