Last Friday, I tried to use my paper trading account and when logging in, I got the following error: Login failed - Failed send NSMsg - javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: timestamp check failed I contacted IB customer support and was told to disable SSL. Duh. Anyway, I don't care much about encrypting my data for the paper account, so I disabled SSL and I could login. But now when I try to log into my real account with SSL checked, I get the same error. Obviously, I don't want to disable SSL. I already empties the Java cache from Java Control Panel -> Temporary Internet Files and re-launched the browser-based TWD (both stable and beta). Same error. Anyone knows what the problem is?
