I'm having certificate errors when using Photrio, typically about once a week or every 2 weeks. Sometimes it fixes itself the next day and today it isn't. I've followed the links on Mozilla and deleted a certificate and replaced it, which has worked previously, but doesn't now. I'm using Windows 7 and Firefox 58. Here is what I see when I try an open phototrio:
Secure Connection Failed
An error occurred during a connection to
www.photrio.com. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
Any ideas what's up? Works fine on Sea Monkey browser. I also have Kaspersky Total Security.
