WebInspect .NET Agent is not detected

After running the following commands on a windows server 2022:

C:\Windows\system32>"c:/program files/fortify/webinspect_runtimeagt_dotnet_21.1.0/tools/iiscontrol.exe" -a DefaultAppPool register restart
Runtime will be registered for the following app pools:
DefaultAppPool
Runtime Platform has been registered successfully.
stopping W3SVC service...
stopping WAS service...
starting WAS service...
WAS service started successfully
starting W3SVC service...
W3SVC service started successfully

C:\Windows\system32>"c:/program files/fortify/webinspect_runtimeagt_dotnet_21.1.0/tools/iiscontrol.exe" status
Runtime Platform is enabled for the WAS service
COR_PROFILER={xxx}
COR_ENABLE_PROFILING=1
FORTIFY_RUNTIME_CMD_FILTER=(aspnet_wp\.exe|w3wp\.exe).*-ap +"?(DefaultAppPool)"?
COMPLUS_useLegacyJit=1
IIS is running
Runtime Platform is not being used by any currently running processes

the agent remains undetected by WI. the IIS has multiple app pools and one of the dedicated ones is serving a LIM if that matters. what could be the issue with the agent?  thanks.
