Ted here from Shopify, thanks for posting your query!
I've taken a look at your domain's set up and I'm not seeing any errors. It looks like the DNS settings are pointing correctly to your store and the SSL certs have been issued. Here's an example of what I'm seeing. Sometimes after purchasing, it can take a domain 24 hours to adjust which might have been the reason you were seeing the error initially. If you are still seeing an error, could you try accessing the store using a different internet provider and device? Please let me know how this goes!
How are you finding Shopify so far? Your store looks fantastic by the way! If there’s anything else I can help you with please let me know, I'm happy to help!
Thanks for reaching out and for letting me know.
I've checked the DNS set up you have listed for the domain and I can confirm that everything has been set up correctly. When I view your site, I'm brought to the storefront successfully for both rosylana.com and www.rosylana.com. As well, I can see that your SSL records have been issued successfully too, as shown in the below screenshot.
Can you try accessing the site using a different device and internet provider such as your mobile phone and phone providers internet connection, instead of a desktop and wifi? If so, are you able to replicate the issue? As well, can you clear the cache on your browser and make sure the browser you are using is up to date? If you are using Chrome, you should be able to do so as mentioned in this guide.
Please let me know how this goes!
That's great to hear! If there's anything else I can help you with, please let me know, I'm happy to help.
