feature request: documentation on how to test server from the outside

[wimdecorte]

Can the docs include some basic troubleshooting info on how to verify if the C2 is reachable from the outside, without having to deploy an agent?
A postman call to the heartbeat endpoint perhaps that details the call to make and the response to expect?

That would help in the 'divide by half' troubleshooting effort. Now I don't know if my agent is misconfigured or if my base isn't listening when I get no pending clients when using 'activate' on the server.

Sure. In the meantime - you would get a 404 on a properly listening endpoint as viewed from the outside.
