I tried configuring roundcube for my mailserver and followed this guide: https://mailcow.github.io/mailcow-dockerized-docs/third_party-roundcube/
I get roundcube login screen but after putting credential, I get following error:

I revert back to backup and followed all steps again thinking there may be issue on one of the steps I followed. Same issue.
On installed screen, I was able to send test email and IMAP login.
Any one has any idea what is causing it?
