AUTHENTICATE PLAIN: Authentication failed

I have the following problem for some time now I was getting the error “login failure” when trying to login to webmail, but after a few attempts I was able to login, now in the latest updates it is no longer possible to login

In the roundcube logs I have the following error
IMAP Error: Login failed for [email protected] against localhost from XXX.XXX.XXX.XXX. AUTHENTICATE PLAIN: Authentication failed. in /var/lib/roundcube/program/lib/Roundcube/rcube_imap.php on line 211 (POST /?_task=login&_action=login)

A way that seems to solve and I set the email password again through the panel, but I have many email accounts

did you upgraded the os from minor to major version ?

no, i continue with the version of ubuntu 20.04 since when i installed hestiacp i only do hestiacp updates

I’m a little afraid to update the OS and have problems in hestia

hestia doesn’t reset the password on its own, you need to have some system admin look into it why this is happening.


I have the same problem. “Authentication failed.” But no reason given. Why can’t I reset the username and password, at least?
