Panel unavailable with advertisers DNS

Hope someone has a bright idea here.
I use an advertising partner (Ezoic) on my websites. I’ve pointed my nameservers to them. Since then, the Panel is unavailable.
With my Kirby 2 install, I get the login panel, but when I click ‘login’, it just refreshes the page.
With my Kirby 3 install, I just get a grey screen (background) - no login panel.

I’ve done a workaround with creating a url. But it’s messy and I want to figure out why the panel doesn’t work.

Happy to hear from you with any thoughts.

How long ago did you point the nameservers? They can take up to 48 hours to fully come into effect. Often if you switch your computers networking to use Googles DNS (or other free ones, google may or may not be gathering data on the sites you visit if you do that). or Open DNS, they often wor sooner then your broadband providers DNS.

About a week ago, so I don’t think it has anything to do with that.
