How to properly set up a 1C server on Linux (Ubuntu)?

Question

linux

Good day, good and happiness to you)
Situevina is like that.
On my computer running Ubuntu 16.04, I installed the server and client 1C enterprise 8.3 . I
chose Postgresql as the database.
The database server is located on a separate machine (virtual machine), but that’s not the point)
Everything works as it should. But, I can't connect to this server remotely.
As I understand it, the problem is in the hostname of the machine on which the 1C server is.
At first, hostname on my machine was only 1 word (for example, user-pc)
I connect to the server by IP address, and by domain name.
Error when connecting:
server_addr=user-pc descr=11001(0x00002AF9): This host is unreachable. line=1048 file=src\DataExchangeCommon.cpp
Where user-pc is the hostname of the machine on which it is installed. And it doesn't matter if I connect via IP or via a domain, the error is the same.
I decided to change the hostname of the machine to the domain I'm trying to connect to. After that, I can't even connect to the server locally. It turns out that somewhere the old hostname is specified either in the 1C configs, or in the database itself. I searched through the files, I could not find ...
In general, tell me how to properly configure the server, machine, so that you can connect to it remotely

Answer 2

Error when connecting:
server_addr=user-pc descr=11001(0x00002AF9): This host is unreachable. line=1048 file=src\DataExchangeCommon.cpp

I solved this problem by adding "user-pc" to the hosts file, with the IP address of course. And I connect via IP.
