I think you are violated Google's Circumventing systems rule. I noticed your affiliate site is using woltcode.de as domain name but "wolt" is maybe registered trademark of wolt.com. Google cannot allow this kind of similar domain name in generall.
Exactly. I would be happy to change the domain name if they bothered to tell me that this is in fact the problem.
Didn't use to be this way.
I hosted a page on AWS S3 bucket exposed to the web, and had my domain CNAME record point to the bucket public-facing DNS name.
Triggered the same Circumventing ban.
