How can I debug curl error further when Apache error.log is not showing any?
(35) gnutls_handshake() failed: An unexpected TLS packet was received.
curl -v https://example.com * Rebuilt URL to: https://example.com/ * Trying 127.0.0.1... * Connected to example.com(127.0.0.1) port 443 (#0) * found 151 certificates in /etc/ssl/certs/ca-certificates.crt * found 612 certificates in /etc/ssl/certs * ALPN, offering http/1.1 * gnutls_handshake() failed: An unexpected TLS packet was received. * Closing connection 0
