DNS Server cannot lookup domain AWS

Hi Everyone,

I have an issue with the DNS service on Windows Server 2019. I have a CNAME record pointing from an internal domain to a domain hosted on Route53. However, this record frequently returns an 'unknown host' error. My server is already connected to the internet, and the record has a TTL 60. Please help me with this case.
