I'm literally struggling with Google App Engine to deploy my Node JS API as I always have a 502 error. I have seen many answers on this topic but none did it for me.
I've found in the log the following error:
"[error] 32#32: *4028 connect() failed (111: Connection refused) while connecting to upstream, client: 184.108.40.206, server: , request: "GET /_ah/health HTTP/1.1", upstream: "http://172.17.0.1:8080/_ah/health"
My idea is to change the upstream IP address, currently
http://172.17.0.1:8080, how can I do so in Google App Engine ?
