Please try to restart "mlmmjadmin" service, make sure it's running, then try to reproduce this error again.

Re: 502 NGINX error after upgrading iRedAdmin to version .9

The response time is not appreciated, no timely help provided. Also after Dovecot upgrade the IMAP authentication is failing. This iRedmail is not a stable product. Moving away....

There are much better products available in market.

Thank You !!

In your first post, the network port is 7790 which is "mlmmjadmin" service.
In this post, the port is 7791 which is "iredadmin" service, you should restart "iredadmin" service instead.

Question: Did you reboot server after iRedMail installation? They both should start automatically after server reboot.
