Thanks, but it still doesn't work outside the local network
If I use the local IP address, it works fine (see "Picture 1")
If I use my main IP address (which works with my other server), it doesn't work (Picture 2)
Picture 1 is using port 80, not 8001. Picture 2 is using 8001. Now, did you restart the HTTP server after editing that file? Apache only reads the config file on startup.
