I've had this app and camera set for exactly 2 days, and now I am getting an "java.security.CertPathValidatorException: Trust Anchor for certification path not found" error. I can't log into the app at all. I've tried uninstalling and reinstalling, same thing. Therefore, I can't even view my cameras!! How can it work fine the past two days, even earlier today, and then suddenly pops up with this error and shut it all down??
