Yes, you are correct I can search for what all the commands do and have done just that for many of them. However, none of my searches have told me what the effect of the command “sudo passwd -d root” does to the web page or the mobile app.
I would like to think it would have no effect, however that does not seem to be the case. It appears to be stopping access to http://x.x.x.x and allows only read access to the mobile app. Something else has allowed only read access to http://x.x.x.x:8080.
My only work-around is to reinstall everything and test every option I want to use before any command. Then a command, try every option again. Repeat this process until I figure out what works and what does not work.
