I have just created a HTTP API and would like to setup a custom domain name somedomain.mysite.com
In Console under Create Domain Name, when I select mutual TLS option and enter truststore URI in S3, using ACM public certificate which I have requested earlier for same domain name, there is an error of Too Many Requests.
Under Route53, there is an A record pointing to somedomain.mysite.com and a CNAME record to validate the DNS for the certificate under same domain. Using the certificate ARN, I have copied the certificate chain as a PEM file and uploaded to S3
I'm not sure where is the exception coming from as I have not done any updates on API Gateway so far
