Route 53 Subdomain No Longer Working

It seems like there might be a mismatch in the DNS configuration between Wix and Route 53, which is causing the subdomain to return the DNS_PROBE_FINISHED_NXDOMAIN error. Please check on below:

1. Verify Name Server Configuration: o Ensure that the domain's name servers (set at the registrar) point to the correct Route 53 name servers. If the domain is still pointing to Wix's name servers (ns11.wixdns.net and ns10.wixdns.net), Route 53 records won't be used. o Update the name servers at the registrar to the four AWS name servers listed in the Route 53 Hosted Zone.
2. Check Subdomain NS Records: o In the primary Hosted Zone, confirm that the NS record for app.mylandscapedesign.com points to the correct name servers for the subdomain's Hosted Zone. o If the subdomain has its own Hosted Zone, ensure that its NS records match the name servers provided by AWS for that Hosted Zone.
3. Test DNS Resolution: o Use tools like dig or nslookup to check the DNS resolution for app.mylandscapedesign.com. This can help identify where the resolution is failing (e.g., at the registrar, Route 53, or elsewhere).
4. Propagation Time: o If you've recently updated the name servers or DNS records, it might take some time (up to 48 hours) for the changes to propagate across the internet.
5. Remove Conflicting Records: o If there are conflicting records (e.g., CNAME and A records for the same subdomain), DNS resolution might fail. Ensure that the records for app.mylandscapedesign.com are correctly configured.
6. Wix and Route 53 Integration: o If the main domain is still hosted on Wix, ensure that Wix supports subdomains hosted on external DNS providers like Route 53. Some configurations might require additional steps or settings in Wix.
