http API request not going through LTM

I have several services that run as APIs, receiving and replying to regular http requests on a non-standard port (i.e. not port 80). I have set them up in our Big IP (3600 running 11.2) but it isn't working correctly.

 

If I telnet directly to the server on the configured port I get a cursor and then an error (for a malformed request) when I hit ctrl-c; this is the expected behavior. If I do the same using the Virtual Server on the Big IP, I connect and get the cursor but I am unable to get out or do anything else (via ctrl-c or any other command) other than close the command prompt.

 

The pool and virtual server are using basically the default configs (I have changed several back to these during testing to eliminate possible points of failure).

 

I haven't been able to find any helpful information regarding this issue, so I was hoping somebody here might have an answer. Has anybody experienced a similar problem and, if so, how were you able to resolve it?

    Try using CURL to check response from F5. Did you check logs under /var/log/ltm ?

    Update: For some reason it started working correctly after a couple of hours. Still not sure what the problem was...there was nothing in the logs regarding this service other than discussing the nodes being seen when I first set it up.
