Hi Experts,

I am trying to configure the SAP_BASIS_CONFIG_OSS_COMM. I am done with the other configuration and we already registered our sap router to SAP but I am stuck in this step New OSS: Create HTTPS Connections for SAP Services (SM59). Whenever I tried to test the connection in SM59 I get the error:
NIECONN_REFUSED(-10). Can you help me with this? 
Here is my logs in dev_icm.
