Hello, yes this is the version I am using, I have tried uninstalling and re-installing but still no luck

I also tried changing my default browser, from brave to firefox and back to chrome all logged in with my google account, I used Iobit to uninstall mailspring each time and disabled my adguard also. The website always said “Your Mailspring is all set” but it keeps returning “Connection Error - Unable to connect to the server / port you provided. (SMTP)”

I have been experiencing this same issue for about 20 days now. Is there a current fix?

I am still experiencing this issue it keeps persisting after reinstalling clearing caches and reauthenticating. What can I do to resolve this issue.
