Issue with Primary/ custom Domain

Hello, I added a custom domain for my webpage, however most of the time when I try using my custom domain address to get to my site I get the following message in the tab: “This site is under development”.
Then sometime it would start working again. The address works every time it is just my custom domain that would stop working. I was wondering if you could point me to what might be wrong. I appreciate your help.

site name :
Primary domain name :

Thank you

@tina Welcome to the Netlify community. This sounds to be either a DNS propagation issue or a local caching issue, or both. I can see that your DNS changes have not yet propagated, so you might give it a few more hours. DNS changes can take up to 48 hours to propagate.

Thank you very much @gregraven for the feedback. What should I do if I still have the same issues after 48 hours?

@tina It looks as though you don’t have to worry about that.
