I can currently use my Internet normally, but programs such as Don't use Twitch, Battle.net, League of Legends. These don't connect.
During the research I was asked about PingPlotter or WinMTR - I should try this out.
There I noticed that I have around 100% packetloss for easybox.local.

Can someone help me fix this?
Looks like a malfunction from the provider, but a router restart or a reset could also help
Then your Easybox simply blocks pings to itself or can't resolve the DNS entry. Since you can connect to everything else, it doesn't have to bother you.
