I'm able to access a newly provisioned Google Computer instance running Ubuntu 16 via Google Cloud Web SSH interface, and also from other Google compute instances (even ones from different projects)
But when I try to ssh into the instance from my home computer, it gives a "Connection timed out"
I already checked UFW, it's set to allow 22/tcp.
The default ssh firewall ingress rule is also set :
default-allow-ssh
Ingress
Apply to all
IP ranges: 0.0.0.0/0
tcp:22
Allow
Not sure what the issue here is. My home network can access other GCE instances via SSH, and this particular GCE instance's web server is also accessible.
It seems specifically SSH connections from my home network is being blocked.

I hoped the command gave us more clues :( . Without looking into your project FW rules and VM network tags is going to be difficult to narrow it down.
As you already mentioned that you have the proper firewall rules I can only think that you haven’t uploaded your SSH keys (from your home computer) into the instance
You can find clear instructions from Google documentation on how to generate these keys and uploaded in link [1]
Once you have done that the correct command to ssh is:
where:
If that doesn't work you should try to contact GCP support, there might be certain things you don't see for example your project might be part of an organization and under a VPC perimeter that prevents the access from external networks [1]
