deploy app on appengine on port 8761

Question

I\'m deploying a Java app that runs on port 8761, and works fine on localhost.
Although when I push to App Engine flexible environment, I get a HTTP 502 server error.

Answer 1

I think you need to use the network settings section in the app.yaml config file:

network:
  forwarded_ports:
    - 8761/tcp

You might also need to set firewall rules in the Cloud Platform Console.
