I set up a VM instance on Google Cloud and connected to it using PuTTY from my windows machine according to this guide: https://www.freecodecamp.org/news/how-to-create-and-connect-to-google-cloud-virtual-machine-with-ssh-81a68b8f74dd/

I was able to use it for a couple of days. However since the last 2 days I can no longer connect to it. Putty displays only blank and after a while the error "Network error: connection timed out" appears.

I have changed nothing since my previous successful connections (except my location).

At first, please check logs at Compute Engine -> VM instances -> click on NAME_OF_YOUR_VM -> at the VM instance details find section Logs and click on Serial port 1 (console). I'd recommend you to restart your VM instance and check the log for any error or warning messages.

After that, have a look at the documentation Troubleshooting SSH and follow the instructions.

If nothing helped, you can try to connect to your VM via Serial console by following this guide, but keep in mind that:

The interactive serial console does not support IP-based access restrictions such as IP whitelists. If you enable the interactive serial console on an instance, clients can attempt to connect to that instance from any IP address.

more details you can find in the documentation.
