Private API Gateway URL is not accessible

Question

I'm doing some PoC stuff around API Gateway, and I can't access the URL that API Gateway gives me after deploying the endpoint.  I have a VPC endpoint set up with Private DNS turned on.  I can access the API Gateway if I use one of the VPCE DNS names and set the `Host` header to the hostname of the provided API Gateway URL.  But if I log into an instance in the same subnet and try to `curl` the URL that API Gateway gives me, I just get this:  
  
```  
$ curl -ivk https://{apiId}.execute-api.us-east-1.amazonaws.com/test  
* About to connect() to {apiId}.execute-api.us-east-1.amazonaws.com port 443 (#0)  
*   Trying {ip}... connected  
* Connected to {apiId}.execute-api.us-east-1.amazonaws.com ({ip}) port 443 (#0)  
* Initializing NSS with certpath: sql:/etc/pki/nssdb  
* warning: ignoring value of ssl.verifyhost  
* NSS error -5961  
* Closing connection #0  
* SSL connect error  
curl: (35) SSL connect error  
```  
  
What am I missing?

I discovered that the version of CentOS on the instance I was connecting with had an older version of `curl` which didn't handle the SSL transaction correctly.  Launching a new instance with the Amazon Linux AMI resulted in a successful HTTP transaction.
