I have raspberry pi 3 using octoprint to access and control my 3D printer. When I’m at home, logged in my wi-fi network, I can access, normally, the octoprint server via internet host (no-ip ddns), but when I’m outdoors, things doesn’t work well. I’m always getting “timeout messages” or “Server is off-line” or “Server is not responding”. I’m forwarding port 80 in a Apple AirPort Extreme, properly configured, as well as port 22 to access via SSH protocol. Accessing Linux environment via SSH protocol from anywhere, works very well. What I’m doing wrong?
