Comment 51 for bug 1828107

Given that a restart of the application is helping and fixes this temporarily. This reminds be of a known issue in rygel, where disable IGMP snooping is the solution if network bridges are involved and rygel can only be discovered after a restart. https://wiki.gnome.org/Projects/Rygel/FAQ

Not saying that this would help anything here. I just want to raise awareness that this might also be caused by other external factors along the network.
