I tried to access my normally working pi through the phone app, during a period when the pi was switched off. The app took me to my router log in page, and would not go back to the normal volumio interface. My pi is working again, and I can use the web page control, but the app will only go to my router login, and once logged in to the router, I cannot see how to get it to go back to the correct interface page. I did uninstall and reinstall the app, with no change to the situation. How can I restore normality please?
Thanks for your help.
I have managed to fix it by going out of home wifi range, starting the app and being able to set a fixed address for the pi. When I got back it found the pi correctly instead of the router.
