Connect a domain you already own not clickable

I have a domain and the nameservers for the domain are pointed toward the correct name servers. And in the past I could add my domain to my 000webhost account and link it to my site. But now the button ‘Connect a domain you already’ is not clickable (see image), does anyone know why? (My other domain name I already linked is still linked.

Does anyone know how I can link my url to my 000webhost site?

(I’m new to the forum so pls let me know if I should have done something differently about my topic)

We’ve removed the feature

So there is no option to link a domain I already own?

Without upgrading no sorry.
If your domain registrar supports domain forwarding you can try that.
