Why can't I create an infobase?

Question

1C

Good day everyone.
Raised on centos 1C Server 8.3.13 ....
Through the administration server 1C connected to the server (by remote ip. Everything is OK).
In the clusters section, I press "Create infobases", enter the data.

All ports are open, no firewalls.
Installed mysql (docker) "connection failed..." => port 3306
Installed postgres (docker) "connection failed..." => port 5432

What am I doing wrong?

Answer 1

The problem was solved by completely deleting all clusters, and accessing it by ip, and not by server name.

Answer 2

Adel Khalitov ,
what will you prove?
if you do nmap of the port outside the server, what do you get?
