Home Assistant

I moved home assistant to a wireless access point because I live at home and my parents are getting a bit annoyed with me having raspberry pi and an old computer that I use as a server in the living room, so i got a wireless access point from the kitchen in to my room, so I could just have it in here, but now home assistant obviously got a new ip so it doesn't work on my cloudflare url yet, but it's acting kinda strange, I can't access it on my computer, and when I type in the ip i got from the local ip address it integration i can't connect through that, and cloud flares says it's not a valid ipv4 ip address, so idk how to get it back on my url
