strange beaviour connecting trougth Configuration server and Tserver

Hi All,
i’m wirking on existing application and i’ve found a strange beaviour connecting trougth

  1. Configuration server
  2. Tserver

Each protocol works with a configured connection for addp and wsb.
Connecting trougth Configuration server if primary and backup ip are inverted respect to SCS, the connection fails and wsb doesn’t work.
Connecting trougth Tserver with primary and backup inverted respect to SCS, connection is open and wsb works correctly.

Can anyone tell me why?
Thamks a lot,
Fabio

What is “wsb”? What method do you using for connecting to the Genesys servers?
