Unable to Integrate SNMP_exporter with prometheus

Unable to Integrate SNMP_exporter with prometheus .
Both the application are running as services on same servers and port also listening .
But the problem is the data not being pulled by Promethues.
It always shows no data found on promethues. Where as with the snmp_exporter URL ,I am able to get the required info.

I am completely new on promethues .
Please help me on the same.
