F5 APM for Windows RDS web access

Hi all,

Hope you are doing well!

We are looking to setup f5 APM for accessing published applications in RDS server.

We were able to successfully access terminal server over f5 webtop. Created a Remote desktop resource under connectivity using remote desktop session host with SSO. For displaying apps in webtop, 

1  created another resource as type remote desktop web access with SSO. However after login to APM, the icon spins for few seconds and shows warning ⚠️.

2. Created using iapp template and added the RDP to advance resource assignment with SSO (enabled in VDI Remote desktop resource). After login , the resource spins for few seconds and then shows warning ⚠️. The NTLM is mapped in iapp. Delegation is set for the computer account. 

I'm both cases, we are seeing same behavior. We are using same SSL across the system. .

For publishing RDS, we have windows server 2019 and published applications as session based. Not sure what else we need on RDS server.

Cannot find any blocks in FW.

Anyone done this type of configuration?

Please not I am not a network engineer. But I can try to get more details if you want.

Many thanks in advance
