SLD_UC and SLD_NUC failed with Is SAP Gateway started?

Hi Experts,

When I am pushing ABAP data into SLD with RZ70, the SLD_UC and SLD_NUC RFC's are getting failed with error "ERROR: SAP gateway connection failed; is SAP gateway started?". I have provided the Gateway host and Gateway port which is maintained in SLD.

Request you to kindly provide your inputs

Please find the attached sccrenshot.

Regards,

LOhith
