Devices not connecting to remote servers

I have a GL-AR750(creta) tethered and working great. I have installed several WIFI devices that connect to the router with no issue. When I tried to install WIFI light bulbs, they connect to the router, but won’t connect to the respective companies server/cloud to function. I had the same issue with a Ting device that requires ports 443 and 80 to be open. I opened them under the firewall settings, but the Ting and WIFI bulbs still won’t connect to their remote servers. My WIFI thermostats work fine. Looking for recommendations.
