I’m getting a weird error when trying to deploy my Vapor project onto GCP App Engine. I was able to deploy it previously but this error just began out of nowhere. I believe it has something to do with my Fluent Migrations but don’t seem to know how to pinpoint this issue… does anyone have any solutions? I followed this tutorial to get it up on App Engine: [Serverless Google App Engine Flex Custom Docker Runtime & Cloud SQL Backend with Swift & Vapor Web API | by Alfian Losari | Swift2Go | Medium](https://medium.com/swift2go/serverless-google-app-engine-flex-docker-runtime-cloud-sql-backend-with-swift-vapor-web-alfian-c8310acfea0d)

Here is the error on the terminal

That error means that it’s timing out trying to connect to the DB, usually because the app is blocked by a firewall

Thanks, I believe you are right and my error lies within my firewall rules and/or sql connections allowed networks configurations within GCP. I must not be allowing the correct IPs connect
