You simply have to change the “Server” value in HKEY_CURRENT_USER\SOFTWARE\Microsoft\MessengerService to m1.escargot.log1p.xyz.
Or you may try to simply put this code in a .reg file and then execute it:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\MessengerService\]
"Server"="m1.escargot.log1p.xyz"
