====================================== Troubleshooting issues on Google Cloud ====================================== This is an incomplete list of issues people have run into when running TLJH on Google Cloud, and how they have fixed them! 'Connection Refused' error after restarting server ================================================== If you restarted your server from the Google Cloud console & then try to access your JupyterHub from a browser, you might get a **Connection Refused** error. This is most likely because the **External IP** of your server has changed. Check the **External IP** in the `Google Cloud Console -> Compute Engine -> VM instances `_ screen matches the IP you are trying to access. If you have a domain name pointing to the IP address, you might have to change it to point to the new correct IP. You can prevent External IP changes by `reserving the static IP `_ your server is using.
