DNS_PROBE_FINISHED_NXDOMAIN
I appreciate that you have included the error message that you have received as that is very helpful! Looking into this, typically the reason that you are receiving this error message may be due to the DNS settings on your domain idit-wisesel.com. Did you purchase this domain from the Shopify platform? Or, did you connect your third-party domain to your Shopify store?
WIth that being said, you can have your store live without the error message by changing the primary domain on your online store to your .myshopify.com domain. This will allow your customers and visitors to load into the online store without any issues.
Looking forward to your response, let me know if you have any questions.
