Can you let me know when or where you see this error? Is it when you're accessing Confluence in a browser or during startup of the Docker image?

Can you let us know what the URL format was that you were using to access Confluence? Did this Docker image work before or was it brand new? Can you share the command you used to create it?

Kind Regards,


Error is captured automatically for Stackdriver in Google Cloud Platform (see photo). Instance is created with yaml file in Kubernetes. URL: Entrypoint, command, installation directory, home directory, etc. as defined in Docker image.
