Certificate Expired or invalid

[Deena Jeyachandran]

Hi All,

Our SSL was about to expire and so recently updated our SSL certificate recently to change the validity for next one year.

After that, Many of our company's clients have reported this error, when they try to open our SSL URL on their Browser(IE & Firefox).

This error does not happen to me or other users within the company network. I checked with few of my friends outside my company network, but they also did not get the problem.

I thought it might be a problem with the Clients computer.
I tried to fix the problem over phone with the following

1. Check date and time on computer and the certificate.
2. Check URL domain matching with the Issued to name in the certificate
3. Checked old certificate exists in Internet Options->Content
4. Install the new certificate manually in the browser through view certificate option
5. Clear Cache state in IE

The above steps did not solve the problem

I am suspecting there could be a problem with the certificate being implemented. But not sure if this could really be the problem as it does not occur for everyone.

Appreciate any help to fix the problem

Regards,
Deena

Why not just have them examine the certificate they're getting from your page? That should tell you what they're looking at.

It sounds like you did not get your certificate signed by a trusted certificate authority or you wouldn't need to be messing around with your clients' certificate stores. It's never too late to correct that mistake.
