IF YOUR "IP" is changing, that's with your provider / and or / Modem!
IF that's what's happening, your hope is to get them to provide a static IP for your modem....
OR use a DNS service, and hope it can keep up.
Reserve address, and port forward...Set it up on 'wired' first, directly. you can't connect out of LAN (192.x.x.x) unless a port forward will connect WAN address to the device, and you may NOT be able to connect if requesting device is only looking for 'https' and your 'send' device is only 'http'...In the attached image ('
ports reserv etc'), the cams are controlled by a 'server', and the reservations etc point to the computer hosting that server. It should work the same connecting to any integrated Cam server, in my experience, but I prefer to customize the feeds a bit.

The cams are also assigned a reserved IP, ('
cams resv') same procedure ... . or the 'server' can't connect... in this case 192.168.1.201-206 or so. I don't want to expose my cam direct link beyond the LAN, therefore the server is employed, using automatic security login.Additionally,
I use a DNS service to keep my IP address 'static'... so my external web pages, etc, cam server link through DNS never changes. You should do something similar if you're directly accessing the cam itself, which I wouldn't do.
Port forward to appropriate cam, otherwise external requests may direct to wrong device, if multple devices use same port numbers.. e.g. port 80.
