Hello! My Domain doesn't work.
I deleted hosted zone and change name servers from other host provider.
After that I created hosted zone and took NS from this hosted zone and paste it to domain Name Servers.
Start Load Balancer, took DNS from load balancer and created two new records in hosted zone A for domain.com and A for www.domain.com with DNS value from load balancer.
And I cannot open site in browser.
Domain already works. I waited one day and the domain worked.
so was it DNS synchronization?
Yes, it was just DNS synchronization.
