I’m having trouble with people who are behind a BlueCoat Proxy not being able to access sites using Let’s Encrypt certificates.
An example site would be www.i7media.net
Users are getting an “invalid certificate” error in their browser. Upon inspection of the certificate, I notice that the Issuer information is different than the actual certificate installed on the site. For example, O = Blue Coat SG900 Series". The certification path shows “Not Found” for the issuer of the certificate.
While I know this isn’t an issue with Let’s Encrypt necessarily, I was wondering if anyone else has run into issues with BlueCoat and Let’s Encrypt.
To clarify, I am not using BlueCoat and I have no access to modify the BlueCoat device in question.
Is there a way to specify which Root or Intermediary CA is used for the certificates I create using Let’s Encrypt? Maybe that would help the Blue Coat device with the trust of the certificate.
