Upload failed with the error

[amrish_deep]

I tried using Upload applet.It was working fine for some time on my server.But suddenly started giving the following error.Is it with the certifcate for SSL.Do I need to do anything to support SSL?

The error which I have got is
javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException: PKIX path validation failed:
java.security.cert.CertPathValidatorException: timestamp check failed

[support]

This error comes from SSL. Your SSL certificate might be expired ? Could you check it ?
You can use WeakSSL add-on to bypass such issue (i.e. accept expired certificate).
