Webmail login issue after server migration

[alimaserrat]

after migration of Cpanel from our old server to new Centos 6 server, our client with SSL can't login at their subdomain of: webmail.example.net/

I have removed the SSL and re-added but still same issue.

after login the page goes to blank page with 500 error. the following is the log and i'm sure i have the right user and pass..

Please make sure you are using correct password to access webmail account.

Hello,

Could you try changing the password for that email account and letting us know if authentication continues to fail? Also, browse to the "History Reports" tab in "WHM >> cPHulk Brute Force Detection" to verify if the account or IP address logging in is locked out by cPHulk Brute Force Protection feature. The option is documented at:

cPHulk Brute Force Protection - Documentation - cPanel Documentation

Thank you.
