  1. Hey, just want to say thank you for writing these.
    I have API access disabled, while trying to run scan with Nessus. Trying to fix it for a while.
    Your solution worked for me.
    But I decided to not starting nessus service in point 3, after reset nessuscli. Instead I run update, which download and upgrade plugins and core components, then I start nessus service, and I was able to perform scan.
