EXT is not working with SAP WebDispatcher

Hello there,

I've setup a SAP WebDispatcher in DMZ for multiple SAP Backend Systems. It is working fine for my SAP Backend and SAP Frontend System but while doing the same for HANA XS Engine, it is giving an error while doing the configuration check (-checkconfig)........ "ERROR: no message server
configured"

wdisp/system_0 = SID=HDX, XSSRV=http://host1:8000;http://host2:8000,

Per SAP Note 908097; i've done the changes but it is still same.

Any idea on how to get rid of this issue in Webdispatcher? All are latest level but no Luck.

Any help is very much appreciated.

Thanking you,
