Error Message: Peer received valid certificate, access denied

Hi,

When I try to open the ownCloud desktop client in my Firefox (48.0.2) browser, I receive this error message:

An error occurred during a connection to oc.n0va.net. Peer received a valid certificate, but access was denied. Error code: SSL_ERROR_ACCESS_DENIED_ALERT

If someone in knows how to fix this error, I would really appreciate your help.

Thanks--

The error log of the apache2 or nginx on the ownCloud server should give you more detailed information.
