Able to reach server by browser, but not apps

1) Stop using self signed certificates
2) Make sure the firewall is not the problem on the server
3) Connect to it with the configured Docker HTTP port. Not HTTPS.

Thanks for the reply. Removing the self signed certificate (and the docker container volumes pointing to it) fixed the problem. I am now able to connect my apps via the http port.

I was not aware that connecting my port to cloudflare was against their ToS. If I can ask, what do people usually do? I've heard of using a VPN on a device to simulate being on their local network, but if I wanted to let my brother have a login and watch sometimes, I don't really want him "on my network" all the time. I'd rather setup a domain or url that points to my server securely.
