Login to server failed
Two months ago I got the error message that “Login to server failed” and prompted me to retry or enter new password. I have five other linked acts and they all worked properly. I had not changed my password and could not get Thunderbird to access the acct. I went into my acct online and changed the password and entered on Thunderbird and everything worked fine...until today. Again getting the same error message and now on two accts. Changed the password online for one and all good still. Changed the other accts password online (same acct that I had problems with two months ago) and it worked fine for two hours. Now it’s telling me again that the login failed. BTW I have all these accts linked on my phone and have experienced no issues whatsoever even when Thunderbird tells me that my password is wrong.

Could I clarify, is this an issue you're running in to on the Thunderbird client? Is this happening when it tries to retrieve your emails?
Do you know who your email provider is? Is it the same for both accounts you've had the issue with? It may be worth chatting to them about it.
Some providers may blacklist a device. Usually this is after repeated authentication failure, but it could be for a number of reasons.
If you'd like to pin-point the issue, I recommend installing a second mail client on the same device, setting up the accounts, and seeing if you get the issue there too. That should narrow down the issue to being with the email server or the email client.
If neither of these help, pop a question in the Thunderbird support at: https://support.mozilla.org/en-US/questions/new/thunderbird
