I am having trouble portforwarding two ports, 443 and 8245 for no-ip.com for remote camera viewing. The port check tool says connection refused. I have portforwarded other ports with no problem, but these do not work. Thanks

With my weak psychic powers, I can't see the port-forwarding rules which you have specified for the (unspecified) camera. I also know nothing about this camera, so I have no idea if ports 443 and/or 8245 are reasonable. Port 443 is the standard one for a secure web server. According to: https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers port 8245 is used for "Dynamic DNS for at least No-IP and DyDNS". Neither of these is obviously associated with an IP camera.
If all you're trying to do is get DDNS working, then why, exactly, do you believe that you need to do any port forwarding? Depending on the (unspecified) camera, you might need to do some port forwarding to be able to talk to it from the outside world, but that has little to do with DDNS configuration.

Which "The port check tool"? Normally, "connection refused" means that you have made contact with the remote system, but there's no server running there which is listening at the specified port number. If you're not running a secure web server on the target system, then that would explain that result for port 443. Similarly, I doubt that you're running a DDNS server on anything, which would explain that result for port 8245.
You seem (to me) not to know what you're doing. It might help if you started at the beginning, and explained what you're actually trying to do, rather than asking what's wrong with your attempt to implement some "solution" to whatever problem you think that you have.
