Recover from ufw not allowing to ssh on port 22 in GCP instance

SSH Firewall

Tried to setup UFW or any other Firewall, but it disallows any traffic to port 22, which doesn't let you ssh to your Google Cloud Platform (GCP) instance? 😖

This article might be your savior. 😎

Follow the instructions below :

  1. Go to your VM’s configuration page. Select the project. Then, Go to Compute -> Compute Engine -> VM Instances. Click the VM you want to recover
  2. Click Edit. Then, scroll down to Custom Metadata
