[URGENT]Fix Cloud Run Egress Issue
Budget: ₹600 – ₹2,000 INR
My container is deployed on Cloud Run and attached to a VPC via a Serverless VPC Access connector that in turn goes through Cloud NAT with a public IP. A custom domain is mapped as well.
Despite the setup, the service cannot reach the public internet—most visibly the MongoDB Atlas cluster. I have already reviewed firewall rules, confirmed the NAT configuration, and inspected container logs, yet outbound traffic still fails (other external endpoints time-out too).
What I need from you
• Pinpoint the exact root cause of the egress blockage—routing, connector, IAM, or anything else—so I understand why it broke.
• Apply the fix live during a screen-sharing session; no code transfer will be necessary.
• Prove success by showing my backend log line that states “successfully connected” when MongoDB connects (0.0.0.0/0 is already whitelisted on the Atlas side).
Environment highlights
– Cloud Run (fully managed)
– Serverless VPC Access connector → VPC → Cloud NAT (public IP)
– Custom domain mapping in place
– gcloud / Cloud Console available during session
Acceptance criteria
1. Container can reach MongoDB Atlas and any other public endpoint.
2. The expected “successfully connected” log appears in real time.
3. A brief explanation of the root cause and the exact change implemented.
If you have solid experience troubleshooting Google Cloud networking—especially Cloud Run egress via VPC connectors—let’s schedule a time and get this unblocked.
