Hello @Daniel Mcglaughlin we are so sorry to hear you're facing this issue. While domain name changes typically take 24-48 hours to fully propagate across the internet, it can sometimes take a little longer for all DNS servers to update.
Also, there might be an error in the configuration of your domain name server (DNS) records. Double-check that the A record or CNAME record (depending on your hosting setup) points to the correct IP address of your web server where the website files are hosted.
