OpenVAS 8 503 – Service temporarily down

Ok, this is a nightmare, when you found out you did something unknown and break your OpenVAS and every time you tries to start a task, you get a 503 - Service temporarily down message. And whatever you do, its not recovering. Most likely you would go reinstall the whole OpenVAS 8. The real issue is that it takes too long to get everything setup, especially if you want EVERYTHING to be ready and good to go. I know, i have been there.
