Cloudflare Tunnel not working after changing router

I created a cloudflare tunnel and it worked perfectly until I changed my router. With the new router, the tunnel doesn’t work anymore.

I tried creating a new tunnel while plugged into the new router, but I still cannot access my docker containers like Nextcloud.

Maybe there is something I need to update in Portainer to account for the router change? I’m fairly new to this whole IT thing, so any help would be greatly appreciated.
