We use Let's Encrypt (https://letsencrypt.org) certificates based on the
domain verification. It appears that your system CA certificate package
is missing the current CA key:

issuer=/C=US/O=Let's Encrypt/CN=Let's Encrypt Authority X3

You can find this CA certificate here:

https://letsencrypt.org/certificates/

The browsers are using own CA certificate database, and the Let's
Encrypt CA certificate is regularly updated there.
