Fix “[Errno 11] Resource temporarily unavailable” in Python 2.x.x?

Question

I have two scripts server.py & talk.py

server.py is supposed to listen to connections & consume data from talk.py

It works perfectly on localhost ie if I run server.py & talk.py in different terminals on the same machine...

a) talk.py asks for a string b) server.py consumes the string from a) & prints it in the terminal that is running server.py

Like I said, the scripts run ok on a local machine, Ubuntu.

When I deployed my server.py to a GCP VM instance it seems runs fine, however, why I ran my talk.py code in on the local machine to connect to the server.py socket via an external web IP address, talk.py give the error code

Seems like a routing/security issue rather than something with your code. This might help: How to port forward Google Compute Engine Instance?
