Hello,

When I install the latest version of iRedMail on my VPS. I have two problems:

1) The MySQLd service does not start. (The .sock is not even created.). I found the solution to fix this problem: https://stackoverflow.com/questions/599 … ied-failed
Except that suddenly, the installation of iRedMail is already done. And so the database side was not done correctly. I can't do this at first either because the server must be "empty"
------- ERROR ----------

---------------------------

2) My second problem is when I go to https://mail.mydomain.com/iredadmin/ I have an Nginx 502 Bad gateway error. I have no idea where it came from. While https:/mail.mydomain.com/mail is working fine.
-----------Log error : ---------
2020/10/31 13:57:12 [error] 164#164: *4 connect() failed (111: Connection refused) while connecting to upstream, client: My.IP.00.00, server: _, request: "GET /iredadmin/ HTTP/2.0", upstream: "uwsgi://127.0.0.1:7791", host: "mail.lizrobot.com"
-------------------------------------------

I have tried using postgresql, however still got the same error for iRedAdmin (502) and when I try to connect to Roundcube with it, there would be "a database connection error".

Thank you for your help
