Problem Description

For 1C:Enterprise systems with many users, a favored approach is to use client/server mode and connect to 1C databases hosted on a remote server from numerous computers or mobile devices. In this type of use-case scenario, some Windows clients may receive the error "No such host is known" during connection, even if the remote server address is correctly specified in the infobase settings. This problem may occur when the client specifies either the server name or IP.

Solution

To resolve this issue, hosts file on the client side needs to be modified. The path to the file in Windows is as follows:

    C:\Windows\System32\drivers\etc\hosts

Open the file with a suitable editor that can modify unformatted files (Notepad is not recommended). Then, add a line in the following format to the end of this file:

SERVER IP is provided to you by the hosting company. It is often the IP that you use on RDP or terminal to connect to the server. SERVER NAME parameter can be found in Administration of 1C Enterprise server x86-64 application under the Central 1C:Enterprise 8.3 servers menu.

For instance, if the server name is TULPAR and its IP is 111.222.333.444, the line to add to hosts file is:

After adding the line, you can either use SERVER IP or SERVER NAME in "Server cluster" field to connect to the server.
