I’ve got a home assistant instance running on RPI 4 and have done for at least 6 months now. And for some reason over these few weeks I’ve encountered an error which is that home assistant loads but it doesn’t connect to the internet and all the integrations that require an internet connection such as the weather just doesn’t work. To solve it last time I had to back up my home assistant and then re flash it on my SSD but why is this happening. I can access the home assistant page on my local network as it’s connected to that but there’s just no internet connection
You’re not giving us much info to go on. Are you using pi-hole or adguard or anything like that? Did the DNS server change maybe, or could the dns server be malfunctioning?
Are you running your pi over wifi or ethernet? Could it have switched to a wifi AP that has no internet?

Hello, Sorry for the lack of info. I finally sorted it in a much quicker way and that was by just restarting my internet and then also restarting home assistant
