Port is closed on Netgear CAX30, I can't use port forwarding

I just have changed Combo moderm router Netgear CAX30 from the old Netgear C7000v2. I setuped dynamic dns using noip and port forwarding on device, but I can't remote access to locally host that I assigned to port forwarding. With router C7000v2 is still operate normally.
I tried to access using domain provided by no-ip to connect locally host in local network. It shows error: 400 bad request. Please help me fix this problem. Thank so much.
