From the topic title, I really cannot confirm that one at least for now.
I also use Hetzner, even dedicated and cloud.
70+ Websites hosted.
All behind Cloudflare.
May I ask, are you using Hetzner as a VPN (Outline?), or at least trying to scrape/crawl the Web with them, as far as it sounds like that to me? (I doubt you’ve setup the Windows Server on the cloud one to access Website over Google Chrome as well …)
Because owners have security measurements due to either webcrawl, webmeup and similar ones hosted at Hetzner which do daily crawl - which either I block.
I even reported them at Hetzner Abuse form, but nothing changed. The saga continues.
In terms of protection, I only allow my servers IP addresses from Hetzner ASN, while I keep blocking other IPs from their ASN that way.
Funny. Wanna bet?
I can provide you a couple of domains to try out with any other provider, even with Hetzner too. The result would be the same
I am afraid no.
Only if you figure out how to contact the Website / domain owner with a good argument/reason why so.
