Unable to access a public url from google cloud platform

[Naveen shetty]

Hi,

I am trying to access a public wsdl from google platform using python 2.7 , it starts with "http://166.XX.XXX.XX :YYYY ". When i am accessing through the local or from the lambda functions i am able to get the response. Inside the firewall rules of app engine i have created another rule to accept the traffic from this IP. Please let me know if anyone faced the same issue.

Hello Naveen, 

How do you try to access the public wsdl? Significant code snippets copied here should help in assessing your issue. App Engine uses the URL Fetch service to issue outbound HTTP(S) requests. You may find more detail on the "Issuing HTTP(S) Requests" documentation page. If this does not exactly address your issue, you are welcome to come back with relevant information.
