TOR , Start and Stop

Good Day Umbrel
I tried successfully TOR access from a Android Tor browser using that provided Tor adress, nnnnnn.onion provided staying within my LAN. I then tried the same adress from the outside. No access. I then tried to close the TOR in the settings but it is stuck.
Is it possible to reset the Umbrel application, starting fresh.
“Something went wrong and the settings could not be changed”., is splashed when I try to move the TOR slider to position No Tor.
