We use postfix and iredadmin for email, and I have updated the php and MariaDB version, then it shows "502 bad gateway" when try to use webmail.
please fix that issue.
Please fix this issue via Teamviewer.
You have to manage SSH, Winscp, psotfix, iredadmin, roundcube.
Admin credentials cannot be shared and Teamviewer access only.
We do not need those who try to change the rate after bid.
