DNS Settings Problem

Hi there

I have a problem regarding DNS Settings… I edited those yesterday because im ready to publish. However If i go to the clients Website (https://www.loewen-oberdiessbach.ch/) im getting forwarded too many times. Did i pasted something wrong into the DNS-Settings?

Thank you for any help…

This is the Website: https://www.loewen-oberdiessbach.ch/

This are my settings.

Here is my site Read-Only: LINK

Okay i figured out, that if i changed the Default-Domain in the project-settings to the “www.”-domain. Its works.

But is that the solution or did i messed something up?
