This morning,I find an error called "A certificate error occured.Please handle CertificateError event".
I have use EO for nearly one year and more than 20 thousands customers are using my tool.So if I want to "handle CertificateError event", I must update all the exe for everyone. that is terrible.
So, why this error? why no error yesterday? Does my purchase outdate?
Please help. Thanks.

Hi,
This event is raised when the browser engine detects that the server's certificate is invalid. For example, the server's certificate may have expired yesterday and that will trigger the problem. If you visit the same site with a regular browser, you will see a message that says there is an issue with the certificate and asking you whether you wish to proceed or not. The CertificateError event is the equivalent of this in EO.WebBrowser. So you can either fix the certificate issue or handle the CertificateError event.
Thanks!

Hi,
We also see this error from time to time. Quite rare and very hard to track down.
We make web requests to more than one server all of them with SSL certs and some are behind a load balancer.
I've verified all SSL certs via my browser = OK
One of the servers happen to be a ADFS server and I'm kind of leaning towards that's the one... but I'm not sure.
Would any inner exception tell us which server throws the error?

Hi David, If you are using our WebBrowser product, then you can just handle WebView.CertificateError event, inside the event you can get the Url through the event argument's Url property: http://www.essentialobjects.com/doc/eo.webbrowser.webview.certificateerror.aspxThanks!
