HI,


We ahve installed Azure based HA clustering solution to cluster ASCS/ERS instances. In ASCS instance, we have intergarted gateway is configured and running. This is to achieve HA solution for RFC connections made from external systems.
Now, when connecting from Biztalk server on to ASCS host and GW service, we see below meesage from gateway log.
*****************************************************************************
*
* LOCATION SAP-Gateway on host <hostname>.<domain_name> / 3301
* ERROR Gateway not connected to local R/3

* TIME Fri Jul 30 12:20:02 2021
* RELEASE 749

* RC 726
* MODULE /bas/749_REL/src/krn/si/gw/gwxxrd.c

We hate tested a successful connection from the biztalk to application server gateway but connecting to ASCS intergarted gateway, we have been getting above message. We did go through all below notes and wiki then configured gateway as suggested. Please find attached ASCS and Default profiles for your review. Let us know if you would like to connect to the system for your analysis. Please help us to understand and setup gateway in HA with in our clustered environment. Thanks.
