Think through the steps you need to take here.

  1. Identify the host by trying "curl stapp0N:6000 for N=1,2,3
  2. Suppose stapp01 is the problem host. Then ssh into stapp01 and become root.
  3. Did “curl stapp01:6000” work on that host?
  4. Suppose it didn’t. What’s running on 6000? Try “lsof -i :6000”.
  5. If something other than httpd is running on 6000, configure it to use a different port.
  6. Check to see the status of httpd. If it isn’t running, restart it.
  7. Does curl give you httpd on that host now? If it does, try jumphost.
  8. Doesn’t work? Maybe it’s the firewell. Try checking that on stapp01.

I went through all the points suggested, still having the same issue.
I’m able to telnet and curl from the jump host.
curl http://stapp02:8087
telnet stapp02 8087

Please help me to fix this issue as I’m not able to move further.
