I have openhab since version 2.
Since some time (openhab 5?) I have issues that my DLNA-Servers are not shown on iOS devices when openhab is active.
I did a lot of testing.
Whenever upd6 is binded to port 1900 (like openhab does), the dlna is not registered successful in network / iOS App Airplayer does not list my minidlna Server.
netstat -tulpn | grep 1900
udp 0 0 239.255.255.250:1900 0.0.0.0:* 1961773/minidlnad
udp6 0 0 :::1194 :::* 1181900/openvpn
udp6 0 0 :::1900 :::* 1960650/java
udp6 0 0 :::1900 :::* 1960650/java
If openhab stopped:
netstat -tulpn | grep 1900
udp 0 0 239.255.255.250:1900 0.0.0.0:* 1961773/minidlnad
udp6 0 0 :::1194 :::* 1181900/openvpn
In this case I don’t have any issues with minidlna.
I tried to find out which services / bindings using upd6 port 1900, but was not able to find out.
In the past with same configuration didn’t had this, but had changes in WLAN (new routers), new iOS-Versions etc.
Can the different bind of Port 1900 ipv4 to minidlna and ipv6 to openhab cause this issue?
