I've been getting reports of users visiting our site getting "this certificate is not trusted" errors when visiting our site via https. I don't seem to ever have any problems, but two separate people on my team have gotten this error randomly when they're on a different wifi network other than the one at our office. They don't have the same problem at the office.
I read up on intermediate certificates but this seems to be just a browser thing, not a network related issue.
I have an SSL cert from GoDaddy, it's on a Rails app running on nginx + unicorn.
Does anyone have any other ideas why this might happen? I'm pretty stumped.
I do get the below (redacted) when running
openssl s_client -connect $hostname:443.
depth=2 C = US, O = "The Go Daddy Group, Inc.", OU = Go Daddy Class 2 Certification Authority
