Two domains - test and "live" but live is still pointing at old servers

[Murray]

Complete Newbie here, so hope this makes sense:

I created a new site (http://archersreference.great-site.net/) on which I built a wordpress front end as a test.

Once I was happy with the front end, I then added another custom domain (archersreference.co.uk) and pointed it at the same file location (after pointing the name servers at infinityfree of course, as a mandatory requirement)

When I ping my custom domain, it’s still pinging to the old IP (92.204.212.181), surely it should now point at 185.27.134.60? How can I fix that?

Pining www.customdoman points to 185.x.x.x as expected, but browsing to that URL goes to the old site.

Confused!
Thanks in advance for any help you can offer.

In WordPress settings, change the Site URL to the new URL. Reload and it should work

Thanks @Greenreader9, but my question isn’t about the wordpress settings, it’s that I changed the name servers, but the custom domain is still pointing at the old site IP several hours later.
I’m going to leave it until morning and check again to see if the propagation has sorted itself out.

Instead you may see: An advertisements page, with ?z being added to the URL. An error saying “This site can’t be reached”. This is usually caused by a system called DNS Caching. This article explains how DNS Caching works, why your website isn’t up yet and what you can do to see your website right now. When will I be able to …
