Hello, Migrating from dynamic instances in Java11 GAE to manual/basic instances results in 403 error when Google services (from IP 0.1.0.3) performs a "/_ah/start" request.
App Engine is configured with Private Service Access and is only accessible from the VPC and specific IP's. No firewall rules apply because it's an internal request from Google but rules were configured for testing purposes. Either in manual or basic mode the result is the same, if we roll back to the dynamic mode it works fine. Does anyone with a similar problem? Thank you in advance.
