Running the IOT Gateway there are 2 options documented for access to the interface.
- Running through *.mozilla-iot.org
- Letting the gateway get certificates for its domain through LE
I seem to be using a third option (that does not work that well)
3. Running a reverse proxy server that forwards to the http implementation
It seems at least one protocol (wss) is used in the Javascript client side that then can not be redirected by the proxy. Most notably during the adding of devices.
Personally I prefer to keep all my servers contained behind a firewalled proxy, if there would be any possible solutions or people who ran in the similar issues I would like to know.
