Mailspring will not authenticate shaw webmail

Mailspring will not authenticate shaw webmail with NordVPN running. Mailspring will only authenticate shaw mail while NordVpn is not runnin, it also authenticates on the wron IMAP port “143” instead of “993”

I have tested as many configurations as I can think of.

Even with NordVpn not running it will only authenticate on port “143”
Please tell me the fix or can you somehow update the app to work properly?
IMAP configuration

Hostname

imap.shaw.ca

Port

Secure connection type

SSL / TLS (recommended)

I have the same issue. I have no VPN. The authentication will only work on port 143.
