NOTE:
The job _not_found issue should to be fixed.
Practically it was caused by the telemetry multiple fails to reach destination (since we've set it to localhost) and was restarting the whole server.
To fix you set any IP that will answer on port 443 with any status code and any ssl cert.
No need to be 200 or whatever, just to be alive and reachable.
We've set the IP to Google's ones, but you can change it to whatever you'd like.
We've tested the solution with long scans , and the issue never happened once.
