sand87ch, some questions to help you isolate the issue:

  • what does the network connectivity from your BIG-IP to your ubuntu instance look like? local subnet or routed? if routed, do you have routes from BIG-IP to the ubuntu instance and vice-versa?
  • On BIG-IP cli, can you ping the IP on the ubuntu server where the services are running?
  • If so, can you curl (assuming http) the service successfully?
  • If so, what does your health monitor on your BIG-IP look like?

You can enable debug to see what the BIG-IP is seeing:

 

tmsh modify sys db bigd.debug value enable

 

Just make sure you modify it back to disable when do troubleshooting.
