Can I just edit my pihole.toml to put it back to the default for port 80? How do I get pi-hole to re-read it's configs and bind to that port (sorry - I can't immediately see anything in the docs about editing pihole.toml).
Please note I am not asking about why the change was made. I don't care about that
You can change the toml file or you can go to All Settings> Webserver & API. Make your changes and hit click save and apply. You will need to be in expertmode to do this.
