Hi Colin,
That allowed me to progress past the error.
Now that I have created the .PEM file, it is 'hanging' at "Uploading instant-server-cert.pem..." I've waited a few minutes, as suggested in the article and refreshed the browser but do not see the certificates and can confirm that I still receive the expired certificate error when connecting.
Just for clarification, the .PEM file that I am creating has the following:
* Contents of the .CER file that Comodo sent to me
* Contents of the CA bundle downloaded from Namecheap as they create the bundles for the various certificates that they sell
* Privatekey.key - I'm assuming that this is the CSR? If not, where would I find this since the original CSR was created via IIS as opposed to OpenSSL?
According to Namecheap, where we purchased the certificate, it states: If you have your certificate in the PKCS#7 format (appropriate mostly for IIS/Microsoft Exchange), you already have your bundle included into your certificate and do not need to install it separately.
Although I can show that this does not work.
Thanks,
Jarrod
