Email accounts don't work

I have email accounts which used to work fine but then suddenly stopped working. I can't log in, with roundcube I get Login Failed, with the others it tells me the password is incorrect, I've changed the passwords in cPanel and when I try to set it up on Android I get incorrect login details, also a mailbox which had quite a few mail went to 0/250MB.

Searched around but couldn't find anything like my problem.

Hello :)

Is it possible the email accounts have been locked by cPHulk brute force detection? Review the "Login/Brute History Report" in "WHM Home » Security Center » cPHulk Brute Force Protection" to determine if any entries exist for these accounts.

Thank you.

Hey no cPHulk was already disabled because it was blocking me logging into WHM.

Is this only happening with Roundcube, or do you notice the same behavior with other webmail clients?

Thank you.

It seems to only be the main domain of my site domain.co.uk that isn't working. My WHM is set hostname to server1.domain.co.uk and i made an account for cpanel for domain.co.uk and for a long time it was working fine.

Could you confirm if this is happening with Roundcube exclusively, or if it also occurs with other webmail clients (Horde, SquirrelMail)?

Thank you.

I did reply, I left one before I left the one about the domains. Clearly the forums here messed up. I said it happens on everything including clients like thunderbird and android.

Could you open a support ticket so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

Thank you.
