No longer able to download email: Authentication failed

It seems to me something changed recently in Thunderbird that results in my receiving this message instead of being able to download my email:

Sending of password for user dave@dianeanddave.net did not succeed. Mail server mail.dianeanddave.net responded: Authentication failed. My Thunderbird logins are in the first attached png file. My email server is Hostgator and my accounts are shown in the second attached png file.

I can still see my email on Hostgator webmail by logging in to CPanel and choosing the dave@dianeanddave.net account. Using Thunderbird's Troubleshoot Mode provides no further information.

I need the convenience of my Thunderbird access restored.

What should be my next step?

I accepted a Thunderbird update from 91 to 102 and that fixed the problem without any other changes.

Thanks for your suggestions.

Hostgator offer these instructions. https://www.hostgator.com/help/article/outlook-eudora-thunderbird-mac-ipad-phone-client-settings

Are you using SSL connections. You should be.

I suggest you consult the more troubleshooting information on the help menu and compare your settings shown there to those suggested by your provider. If you have an antivirus scanning mail disable all mail scanning as a test. Generally disabling all third part anti virus is a recommended step in diagnosing issue as they are prone to messing in the mail nest.
