Hello Rozal,
It seems okey.
sap1 and sap2 are node names.
for ADS you virtual DNS is *adsprd.
You can use http://..adsprd:50400/.. url to reach the mentioned service.
Did you try reaching the service using this URL?
What is the result? If there is error can you send screenshots?
Try the service after you move SAP P* service to other node also.
