Can't connect using remote UI

[NFedorenko]

Hello to all.

Got a strange thing - I've copied my main project to another machine.
I've changed data and event in config filefor a new machine.
I've changed systemname and sysID and project name.

Everything works great on new machine.
But now i can't connect to this machine using remote UI.

In logs I got:

WCCOAui (13), 2018.12.17 15:54:17.983, SYS, INFO, 0, , Connection from newMachine expired

WCCOAui (13), 2018.12.17 15:54:17.984, IMPL, FATAL, 5, Connection not possible, WCCILdata

On machine I can seethis in log:

WCCILdata (0), 2018.12.17 16:03:32.045, SYS, INFO, 4, Connected to (SYS: 56 Ui -num 13 CONN: 1(R)) @ ::ffff:xxx(my IP)

WCCILdata (0), 2018.12.17 16:03:32.052, SYS, WARNING, 39, Connection lost, MAN: (SYS: 56 Ui -num 13 CONN: 1(R)), Connection reset by peer (10054)

So I got a connection but it expires.

What can be a reason and how to solve that?

Maybe the hostname/IP resolution does not work properly and therefore the connection gets lost.
Have you defined the hostnames and IP-addresses in the hosts file of the operating system?

Solved. There should be IP addresses with names in hosts file on both machines (server and remote ui machine)
