Message or sequence monitoring in SOAMANAGER

I'm a basis guy and I was contacted by my PI guy because he cannot setup message or sequence monitoring in SOAMANAGER.

Here gets a Service cannot be reached and a error code 403 for reason forbidden.

I get the same issue when testing.

I'm trying to determine if I am missing a service activation or is it authorization.

I can run TCODE SXI_MONITOR from ABAP and see the screen

When calling it from SOAMANAGER, i get an error.

My URL looks the following

http://sd01cudb0014.omega.dce-eir.net:8000/sap/bc/gui/sap/its/webgui?~transaction=SXI_MONITOR

What am I missing??
