Custom domain in netlify doesn't update the deployed code

Hello, I am trying to connect my netlify websites to my domain. I added the nameservers, and netlify said all is good. However, when I open the website by domain, it shows either an an old page, that was standard page by the domain provider.
Why I can’t see the deployed content?
can you please provide any solution? Thank you

Hi, this is likely a propagation issue. Has it been more than 48 hours since updating the domains for your site? If not please wait 48 hours.
