• shared experiences: raspiblitz/raspiblitz#214

• if Nginx breaks: sudo nginx -t is a very useful debug tool. Runs a test and displays detailed info on which line in the configuration is problematic.

• Try to run the commands manually one-by-one, spot which is causing the problem and copy the output
