I want to access my media files from anywhere on the world, so I thought I could set up some UPnP/DLNA server, add media files to it, then access these files from any UPnP/DLNA-capable device.
Therefore, I have installed MiniDLNA / ReadyMedia on my public Internet-reachable Ubuntu 16.04 machine, which is available under the domain name
example.com. I have also opened TCP port 8200 and UDP port 1900 on that machine - basically I followed the steps in https://help.ubuntu.com/community/MiniDLNA .
I can visit MiniDLNA's web interface from any client by visitng
Now I would like to access the UPnP / DLNA service with some client, e.g. VLC on my Windows machine or Android smartphone.
But when pointing any of these clients to
http://example.com:8200, they don't show anything.
