How long does it take for nameservers to add your site?

I changed the nameservers of my domain (xxxnoscopemlgxxx.com). The nameserver change has already propagated but the nameservers time out.

You can see here that it is connecting to the correct nameservers but they are just timing out. The email I used to make an account is on the same domain so I don’t have a way of receiving emails until I get the nameserver situation taken care of (I don’t know if I have been sent a confirm email about the domain being added or anything like that)

It’s already been a couple of hours and I already have WordPress installed as well as an SSL cert but I just can’t access my site until the nameservers start returning an IP.

Is this something that will resolve on its own or did I mess something up?
