When client app calls the IIB (v9.0.0.5) HTTP JSON service, getting the following timeout error, but runs fine while calling from Soap UI/Nettool utiity

Increase the speed of the flow, or increase the maximum client wait time for the nodes using this URL.

Request doesn't even get into the actual flow, just times out. Please let me know if I am missing anything.

Thanks

What have you done to troubleshoot the connection?

What have you done to troubleshoot the client request parameters?

can you telnet to the http listener port from the client machine?

What is the connection timeout on the client side?

Yes. Same port accepts SOAP & HTTP connections.
Works for SOAP services.

Using HTTP listener as an embedded listener.

Time out on client side is 120 sec, as defined on HTTP input node.

Thanks

So the error message says

Increase the speed of the flow, or increase the maximum client wait time for the nodes using this URL.


This means that the flow downstream of the HTTP web server (the actual HTTPInput node) did not fetch the pending request from the webserver (the httplistener) before the node timed out.

So perhaps the message flow is running in a single instance and it's too busy to process new messages. (or at least the part of a message flow that starts with an HTTPInput ndoe)

Perhaps the HTTPReply node didn't get called, or didn't get called in time.

Perhaps you need more instances. Perhaps you need to optimize code. Perhaps you need to tune the threads of the http listener...

Even after increasing the instances of the flow, we are receiving the same error.
Service works fine with SOAP UI utility with out any issues. Receiving timeout when calling from Datapower.

Thanks
