Hi @Prissie
Thanks for reaching out here with your issue, and also welcome to the Shopify Community!
I understand that you have connected your domain to your Shopify store, and have noticed that others can access it, but you cannot. That is certainly an interesting situation, and I would be happy to help you troubleshoot it here!
That is very exciting about the store launch - how is the store setup going so far? Besides this domain query, are you experiencing any other difficulties?
Thanks for confirming that your domain host says all looks OK on their side and for outlining all of the various troubleshooting steps that you have tried. I understand the desperation here, I am sure I would be the same - don’t worry we are always here to help steer you in the right direction.
I checked the URL you provided of www.dooek.com and it does seem to be working OK for me and is redirecting to the https://dooek.com/password URL as you would expect. How long has it been since you set this domain up on your store? Sometimes it can take a few days for domain/DNS changes to propagate across the internet, so that is a possible reason that it isn’t working for you yet. However if it has been more than 48 hours then it is unlikely to be the reason for this issue.
It sounds like you have already tried a lot of local troubleshooting steps to try to rule out your own setup. One thing I am wondering is if you have tried using a completely different network such as a mobile network if you have been using Wi-Fi or vice versa. It might help to rule out issues with your internet service provider or specific network setup.
Were you using this domain for anything prior to connecting it to your Shopify store? One thing worth checking is that DNSSEC (Domain Name System Security Extensions) is inactive on the domain, because if it is active it can technically cause some resolution failures. DNSSEC is usually only used if you have a custom nameserver configuration. If you are managing this domain from a third party host, then you would need to contact them to inquire about turning it off.
