Thunderbird has stopped pulling my IMAP mail from one account
Every time I read or try to pull new emails for one of my accounts in Tbird I get this error:
"Server [SERVER NAME] has disconnected. The server may have gone down or there..."
A few facts:
- I have not changed any settings before this began
- I have various other email addresses pulling from the same IMAP server/port without issue
- I spoke with the host, they see no issues on their side
- I have not changed my password
- I can log into Webmail successfully and pull mail just fine
- It did connect once and pulled a couple dozen old emails which now have a current timestamp
- I cleared my cache/history
- I deleted the IMAP account and made a fresh one, same thing
- I can send mail successfully

My only thought now, could it be my ISP?

Oh, I don't think it's my ISP because the same IMAP info works on mobile.
Please post your Troubleshooting Information.
At the top right of the Thunderbird window, click the menu button 
, then select Help > Troubleshooting Information.
Press the "Copy text to clipboard button" and paste the information into your reply.
If there are multiple accounts, please indicate which is the troubled one.

Account 52 is the offender.
The server settings for account52 look good to me, and for the incoming server are identical with the other 1and1 accounts. Only for the outgoing server, some accounts use SSL/TLS port 465, and others use STARTTLS port 587. In any case, that wouldn't be related to your problem with receiving messages.
I'm a bit at a loss with this. These are some generic troubleshooting steps for problems with receiving messages. https://support.mozilla.org/kb/cannot-receive-messages
Also, this may well be a problem with your email provider's server. You may want to check with them again. Webmail uses an entirely different infrastructure. So while webmail works, this is not necessarily an indication that there's nothing wrong with IMAP, and SMTP servers.
