Dear all,
since yesterday my application access within WebVPN is not working anymore (but last week it has been working). The Java window does not show the applications anymore but only a red "x". The Java console window shows messages like
"java.io.IOException: Invalid keystore format" and
"javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: Plugin couldn't trust Server".
The concentrator's log shows messages SSL_ALERT_CERTIFICATE_UNKNOWN
I am using JRE-Version 1.4.2_04 (downloaded from the concentrator) on W2KSP4. Neither reinstalling the JRE nor VPN3000 software upgrade to 4.1.2 solved the problem so far.
I have noticed that the "Sun" certificate is valid until 2nd June 2004 and it is installed in the "other persons" store. The publisher of that certificate (VeriSign Class 3 Code Signing 2001 CA) can't be found.
Any ideas what happened and how to solve the problem ? Any hints are highly appreciated. Thank you very much.
