Subject Re: Hosting API's on Nifi

Aside from opening another port I don’t se how you can overcome this issue. HandleHttpRequest
essentially starts another web server and this server needs a port to listen on.
Further more, there are many other network based Processors that come with NiFi that would
fall int the same category - “a processors that need to bind to a port” to facilitate
communication with external systems, so I’d recommend bringing this up with your AWS admins.

I know there is nor much help in my reply, but I hope you understand.

as the webserver uses that port to serve the canvas. So if we provide any other randon number
then it works fine.
