[SOLVED] Web adress not allowed

A Venue we use to visit (for musical rehearsals) has the Web adress www.musikakademie.bayern/
This adress is existing and reachable but it can not be entered into the Web adress field of the venue. (in Backend)
I think the first level domain ".bayern" is not listed somewhere.
Can i do anything to make it "allowed" ?
Joomla 5.1.2 JEM 4.2.2
thank you

as quick fix:
you've to change admin/tables/venue.php

if (!preg_match('/^(http|https)/\/[a-z0-9]+([\-\.]{1}[a-z0-9äöüáéíóúñ]+)*\.[a-z]{2,5}'

to
