I cannot connect after installing my certificate
If you cannot connect and "SSL Error: The root CA certificate is not trusted for this purpose" is logged to the server log, this is usually due to having an incomplete certificate bundle.

Please export the certificate using Firefox and try again. Chrome and Safari are known to create incomplete certificate bundles.
