Hello @anrunie

Can you provide some details on the matter, are you trying to configure Branding for your project?

If so, than in case you’re using HTTP domain, please switch to HTTPS

Yes, I am configure the branding. I do not understand the “switch” to HTTPS, my domain can only use HTTPS and in Cloudflare I configure it to only permit HTTPS connections.

Can you provide me with a full domain you’d like to add? Is it available in web, or it belongs to closed system?

If system doesn’t accept the cname you’re trying to add, please try another one.

The domain works now. It is a CF configuration problem. Thanks!
