In my work network I am running 2 node-red instance on 2 different PC's. The Node-Red installation is a global install so any windows user can access the same node-red instance.

Using the TCP nodes i am tryin to send data from one PC to another and on the tcp request node I am getting this error in the debug

HTTP/1.1 400 Bad Request
Connection: close
