Google Cloud Shell VM not starting

I have a Google Cloud project with billing enabled but consuming no resources at the moment. I would like to deploy the project with Google Cloud Shell but I cannot get the shell to start. I see a "Provisioning your Google Cloud Shell machine" message which lasts a few minutes, before I get a random error, typically a 502.

I have tried different browsers, clearing the cache, incognito mode and the Google Cloud app on my phone. I have also disabled all security on my router and added console.cloud.google.com to my allowed list. I have even tried on my cellular network.

If you are experiencing issues while starting Google Cloud Shell and receiving 502 error, there are few troubleshooting steps you can try.

In the Cloud Shell Menu, you can select Restart and a pop-up dialog will ask for confirmation on Restart Cloud Shell. After this, a new VM shall be provisioned for you to use.

1. You can also do safe mode to login as root and check any problem in your .bashrc or .tmux.conf files, to see documentation click here.

2. After doing safe mode, if necessary, you can also get a completely new cloud shell state by following this link.

Also you can try to set up Google Cloud SDK on your computer and use your terminal/shell. Switch to Ephemeral Mode. Please notice that it is a fresh env and does not maintain any persistent state between sessions.

For more information you can check this official documentation. If the issue still persists, kindly contact Google Support.
