Connection with customer domain not working

Dear Webflow Community,

I set up a company website on Webflow and now tried to connect my customer domain www.123leergeräumt.de with Webflow. Since I already have two other websides
successfully connected from Ionos to Webflow I am familiar with the process and set up the DNS settings correctly.

Nevertheless I am not able to add the customer domain at the ‘’Publishing > Production” section on Webflow. When clicking on “add domain” nothing happens.

I would be very glad if you could provide me with some potential steps how to fix the problem.

If you need any further information, please let me know.

Best regards


Here is my site Read-Only: Webflow - 123 Leergeräumt

Hey Felix sounds like a hosting or app-level glitch in Webflow’s site settings.
But before contacting support, I’d try;

  • Try a new machine, on a different network
  • Disable any browser add-ons
  • Clear your browser cache

Once you’ve ruled out network, proxy, firewalls, browser add-ons, browser cache, there’s not much left except the server itself.
