Thunderbird keeps asking for password for 3 email accounts several times

The error message saying that the login to bell server failed.

Did you verify all your mail server configuration according to https://support.bell.ca/internet/email/how-to-use-bell-mail?step=5

yes I have check the accounts and they are set with the following: imap.bell.net port 993 connection security ssl/tls authentication method normal password

outgoing server server name: smtphm.sympatico.ca port 587 connection security: starttls authentication method normal password

please note I have Asus Router with total protection pro with vpn. Windows 11 Pro. I have not setup two way authentication for any of the accounts. I have to enter several times the password (it is like in a loop) and uncheck Password Manager Saving (because I do not want it) and then start clicking on the cancel button several to finally login. How can I fix this. It should be to enter a password for email account once not several times. please help. thank you for your response.

also it no longer says it has failed, but the above issue still exists.

I would start by disabling the VPN. Bell probably only accepts mail connections if you connect via their internet and the VPN hides that.

Still an issue?

yes it still happens. I enter my 3 email addresses and then passwords without password manager check. then it asks again with the password manager checked (which I uncheck it) for all three then it keeps asking again. I then start press cancel 6 times and I eventually am in.

Is there any way I can enter it once and avoid this. I have an asus router that has total protection pro and vpn (nordvpn) within it. it is great, but for email there is a problem.

is there anyway that it can be fixed otherwise, I would have to uninstall thunderbird and us my service provider web mail directly.

thanks for your response
