No user can logon via the AWI. The following exception is shown:
Release : 12.3
Component : AUTOMATION ENGINE
The certificate was issued for Server_A, but the hostname= in the ucsrv.ini section [TCP/IP] was set to Server_B which can be an alias.
Therefore the connection through the REST API (JCP) was not possible.
The host= in section [REST] needs to be set to the same name the certificate was issued too, i.e. host=Server_A
