|Status code:|503| |Status message:|Service temporarily down

When trying to start a scan, I get the following error message -

Results of last operation

Operation: Start Task
Status code: 503
Status message: Service temporarily down

I have deployed OpenVAS to the Azure cloud on Ubuntu 18, so I am not able to deploy the preconfigured image.

How can I resolve this problem? last night it was working, today it just seems to have fallen over.

It’s likely that the scanner (openvasmd) is not running or reachable.
