Cannot connect to DevBox instance.

Question

I setup and configured an Azure DevBox instance. It has been running without any problems for the last month.

I tried to connect today, and can no longer connect, it gives me a reconnect error. Additionally, I get the following error from the web access logs.

Sending Trace to using JS Delegate with eventName=ConnectionException, trace message=An exception has occurred. Details: disconnect code=OrchestrationResourceNotAvailableError(10010), extended code=<null>, reason=The orchestration POST failed with status 400 and error E_PROXY_ORCHESTRATION_LB_NO_SESSIONHOST_AVAILABLE message: The service couldn't connect to the user <redacted device name> because the session host <redacted device name> is unhealthy. Either resolve the session host state issue or remove the session record after you've ended the user session. This will allow the service to connect the user to a healthy session host.

I tried the Azure CLI repair command multiple times, as well it is the only way I have to access the machine.
