How do I know which IP address of an Azure App Service to whitelist in Google Cloud SQL

I have an Azure App Service that needs to communicate first to a Google Cloud SQL database. I already "whitelisted" an IP address (obtained from Custom Domains) of that App Service in Google Cloud SQL db instance. However, the Azure App Service always throws a db connection timeout.

I'm assuming that I whitelisted the wrong IP address. I checked the Properties of the Azure App Service and saw some outbound IP addresses. Should I whitelist the outbound IP address too or is their a more correct way to whitelist the Azure App SErvice to be able to communicate with Google Cloud SQL?

Thanks for the help!

UPDATE

Solved by whitelisting all outbound IP addresses of the Azure App Service.

This was solved by whitelisting all Outbound IPs of the Azure App Service. In order determine the Outbound IP's of your App Service:

  1. Go to your App Service
  2. In the Settings (left-side nav), click Properties.
  3. Check Outbound IP addresses text field and you will see a couple of IP addresses there.

Next,

  1. Go to your Google Cloud Console, select a project and proceed to SQL.
  2. In SQL, select your instance.
  3. Go to Connections
  4. Set the Outbound IP addresses from Azure App Service in the Authorized networks of your GCP Cloud SQL.

Hope this will be a big help to others.
