Public ip changed now unable to access frontend

Hello There,

My problem is as far as I can tell cause by my ISP but I thought I would see what others say. I have HASSIO, with duckdns add-on. My ports are forwarded and my frontend has been accessible from anywhere for the last several months maybe years? Lost track of time. Anyway all was working until my public IP address changed. Duckdns updated the ip but I cannot access the frontend. However I know it is accessed. My home assistant companion app still receives notifications and Alexa still functions using HASSKA. On another note my VPN has also gone down. I can no longer access my network via VPN. As far as I can tell there is nothing in the logs.

Your computer/phone might have cached the old IP address, even though Duck updated it. It might not have asked Duck for the new IP, thinking the one it already knows is the correct one.

Try to connect using the IP address, not the Duck DNS name. If the IP works, you probably need to clear your computer’s DNS cache, so it’ll reach out to Duck for the new IP address.

Thanks for the response I tried that. Still nothing.
