In reply to your questions: 

1) You can specify network settings in your app.yaml configuration file, 
for example:

network:
  instance_tag: TAG_NAME
  name: NETWORK_NAME
  subnetwork_name: SUBNETWORK_NAME
  forwarded_ports:
    - PORT
    - HOST_PORT:CONTAINER_PORT
    - PORT/tcp
    - HOST_PORT:CONTAINER_PORT/udp

Related details may be read on the "Configuring your App with app.yaml" 
page, "Network settings" sub-chapter 
<https://cloud.google.com/appengine/docs/flexible/custom-runtimes/configuring-your-app-with-app-yaml#network_settings>
. 

2) In fact, there are many vendors offering managed database services such 
as mLab for MongoDB. These vendors handle hosting, configuration, and 
maintenance of databases. App Engine can connect to these external services 
over the Internet, in the same way as other public clouds by using that 
service's public IP address, in particular the IP address of your MongoDB 
instance. More detail may be gathered from the "Using Third-Party 
Databases" online document 
<https://cloud.google.com/appengine/docs/standard/python/using-third-party-databases#databases_managed_by_a_third-party_vendor>.
 
How did you fail to connect from the standard environment, exactly? What 
were the errors returned? How did you follow the MongoDB connection 
instructions in your app?
