Cannot connect to IPS - 7.1(8p1)E4.

Guys this is my first attempt at setting up IPS and I am obviously missing a trick. No matter what IP address I apply to the sensor I cannot attach.

I am expecting to be able to attach to the IPS via the FW inside interface. Thanks in advance

Tried the following IP settings. Even tried 192.168.205.3/24,192.168.205.2 (ASA inside)

Traffic is obviously detected but I am missing something

Sorry forgot some basic info. The error message reported is

"Error connecting to sensor. Error loading sensor"

The ASA can reach the Gateway 205.1 and itself 205.2 obviously.
The IPS can ping itself 205.3 . 205.2 and 205.1 fail

Not sure if your problem is with the configuration of the Management interface or not but the below configuration is how we have the management interface configured on one of the 5545-X ASA's with IPS we manage and I'm able to connect via ssh to the command line and through the GUI too. Your service host settings look ok to me, although we do not have

sshv1-fallback enabled on any of the IPS devices we manage.
