as described above, LibreElec does not "see" the DLNA server in my network after a shutdown or restart. Actually the workaround I am using is to activate the UPNP SERVER (!)in LibreElec´s settings, after this the DLNA server where LibreElec is connecting to is accessible.
After a restart, I have to deactivate the UPNP Server again in LibreElec, to see my DLNA server. What looks a bit strange is the fact that the adress of the DLNA server is stored as IPv6 in LibreElec, I did not have IPv6 activated. Also sending a wakeup on network is not possible as LibreElec cannot connect to the IPv6 adress.
Any idea where this is coming from?
