Gnutls_handshake() failed: Error in the pull function

Using the curl -vvv command generated in my personalized API documentation, I get the following output:

  • Trying 3.230.102.85…
  • Connected to api.airtable . com (3.230.102.85) port 443 (#0)
  • found 148 certificates in /etc/ssl/certs/ca-certificates.crt
  • found 594 certificates in /etc/ssl/certs
  • ALPN, offering http/1.1
  • gnutls_handshake() failed: Error in the pull function.
  • Closing connection 0
    curl: (35) gnutls_handshake() failed: Error in the pull function.

I’m making the call from an Ubuntu 18.04 LTS VM.

Running openssl s_client -connect api.airtable . com:443 results in:

CONNECTED(00000003)

Is there anything special we should know about AirTable’s SSL certs?
