I appreciate that you have included your online store URL and the specific error message you received! When I navigated to your online store mentioned, I did not receive any specific error messages.
Just to gather some additional context, are you still experiencing this error message, by any chance?
Typically, if you receive the error message This site can’t be reached - it may be due to the DNS settings on a third party domain. Or, the domain will need to complete the set up process to have it properly pointed towards your online store.
