Just choose Europe from the dropdown menu above the "play" button in the Blizzard app.

If @Wilfred has the same bug as me, this won't work. The bug showed up after installing a new language pack.
I had to set the server to asian to get on the european server and the language to german as workaround (even with Server = europe it didnt work as long as the lang wasnt set to german).
I fixed the bug by reinstalling the language packs. If you wanna go with the workaround because reinstalling doesn't always work, you might have to test out what combination of server and language gets you, to your realm.

Or if you don't have the bug, just setting to europe works.. yeah
