There is a strange thing indeed: the server has actually no firewall, however the 1900 UDP port, which should be open for SSDP seems closed.
Here it is the result of some investigation

No idea why MiniDLNA does not check the port.
i just installed minidlna and got it working from vlc over wireless. it didn't work at first. "systemctl status minindlna" showed that it wasn't able to identify the network interface i provided. i have no idea why(old method in minidlna?). i commented that line in config back out and made sure minidlna could read my testing media directory and it worked at that point. i used nmap -sS -sU -T4 -A -v 192.168.1.1 to see if port 8200 was open. it was.
so, if "systemctl status minidlna" or "journalctl -b" shows no problems for minidlna then maybe test with nmap from both wired and wireless and see if there is a difference. If there is, then you have network config issue. the arch wiki page for minidlna has a section about wireless in the troubleshooting section i notice.
