I got a problem with Ubuntu Server 16.04 on dual stack (IPv4/v6).
When I request IPv4 only servers, like Paypal or DockerHub, I got TLS handshake timeout:
$ curl -vvv https://paypal.com 130 * Rebuilt URL * Trying 18.104.22.168... * Connected to paypal.com (22.214.171.124) port 443 (#0) * found 173 certificates in /etc/ssl/certs/ca-certificates.crt * found 692 certificates in /etc/ssl/certs * ALPN, offering http/1.1 * Operation timed out after 0 milliseconds with 0 out of 0 bytes received * Closing connection 0 curl: (28) Operation timed out after 0 milliseconds with 0 out of 0 bytes received $docker pull nginx Using default tag: latest Error response from daemon: Get registry-1.docker/v2/: net/http: TLS handshake timeout
My IPv4 connectivity work at glances, but I don't understand why I got these TLS issues.
Any Idea to help me ?
