Minecraft Dungeons refuses to connect to the network, similarly to a report I filed about the Minecraft Launcher not connecting to my network.

The difference with Dungeons, however, is that it does work in other locations, but it doesn't work at home.

When I open the Dungeons launcher, an error occurs, as seen in a screenshot, where it says "Unable to verify what products you own. Please check your internet connection" and a button that says "TRY AGAIN".

Again, reported to community support and they couldn't help me either.
