SAP_BASIS_CONFIG_OSS_COMM [New OSS: Create HTTPS Connections for SAP Services (SM59)] SOLMAN 7.2

[tan_michael]

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.

Dear Customer, 

The NIECONN_REFUSED error indicates the incorrect router string. It's needed to verify with the SAP network team the correct router string from the configured system to SAP links. 

Best regards,

Dear Customer, 

Error "NIECONN_REFUSED" is a pure network error that indicating the connection error from the configured system to SAP links. The router string should be wrongly used. Please verify with XX-SER-NET team for the correct router string for the system. After getting the correct router string, please create a new tasklist to see the result. 

Best regards,
Vera Jiang
