Hangfire Start Requesting Loopback address

Hi,
I have two servers server1 and server2 siting behind load balancer. Both the server running a Asp.net core same instance service which starts hangfire. For most of the time hangfire starts Requesting as
“Request starting POST http://Loadbalancer/Service/v1/aus/batch/150/run application/json; charset=utf-8 4”
and after sometime start Requesting “Request starting POST http://127.0.0.1:27429/AUORDERSERVICES/iisintegration 0”.
At that time it just stuck there until app pool get restarted or externally trigger hangfire

Please let me know if you have further question.
