HASS not accessible on Raspberry Pi anymore

Hello, I am quite new to the world of home assistant and raspberry pi. A few weeks back I installed Hass.io on my raspberry. However, since then I had to change the wifi router it was connected to as the router was failing often. Even though I kept the credential of the new wifi system the same, I am unable to access hass.io anymore and I don’t know how to reconfigure it. Can someone help?


Sounds like your Pi has a different IP address… try fixing that.

The Pi doesn’t even show up on my new router. It can’t even read it… Is there a way to reinstall hass?
