Self signed cert in chain from only some servers

[Caitlin]

I have multiple Intel NUCs out in the field that I use for displaying digital signage. Out of the thousands I have in the field, a couple complain with this error:

SSL certificate problem: self signed certificate in certificate chain. More details here: http://curl.haxx.se/docs/sslcerts.html, curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.

I've confirmed that the cert is not expired, and the domain name matches

These units are running on Debian 7

Could the network they are on cause this issue with some sort of firewall setting?
