 * When I try to reauthenticate Dropbox I get an API (59) error. Any ideas what 
   might be going on?
 * BackWPup version 3.1.2-beta3 (same problem on 3.1.1)

 * Hello Mossalot,
 * Interesting, because i have copied the cipher list from the Dropbox PHP SDK. 
   In 3.1.1 the list was not integrated.
 * The Cipher list is:
 *     ```
       curl_setopt( $ch, CURLOPT_SSL_CIPHER_LIST,
       						 'ECDHE-RSA-AES256-GCM-SHA384:'.
       						 'ECDHE-RSA-AES128-GCM-SHA256:'.
       						 'ECDHE-RSA-AES256-SHA384:'.
       						 'ECDHE-RSA-AES128-SHA256:'.
       						 'ECDHE-RSA-AES256-SHA:'.
       						 'ECDHE-RSA-AES128-SHA:'.
       						 'ECDHE-RSA-RC4-SHA:'.
       						 'DHE-RSA-AES256-GCM-SHA384:'.
       						 'DHE-RSA-AES128-GCM-SHA256:'.
       						 'DHE-RSA-AES256-SHA256:'.
       						 'DHE-RSA-AES128-SHA256:'.
       						 'DHE-RSA-AES256-SHA:'.
       						 'DHE-RSA-AES128-SHA:'.
       						 'AES256-GCM-SHA384:'.
       						 'AES128-GCM-SHA256:'.
       						 'AES256-SHA256:'.
       						 'AES128-SHA256:'.
       						 'AES256-SHA:'.
       						 'AES128-SHA'
       			);
       ```
   
 * You must find out with is not supported on your server and install it. Or deactivate
   the security with 3.1.2 and the mini plugin from [http://wordpress.org/support/topic/dropbox-api-35-unsupported-ssl-protocol-version?replies=34](http://wordpress.org/support/topic/dropbox-api-35-unsupported-ssl-protocol-version?replies=34).

   cipher in list_

 * I also have the same error. I have the better wp plugin installed, is there some
   sort of interaction error with this plugin?

 * I also have the same error on three of my sites now:
    ERROR: Dropbox API: (59)
   Unknown cipher in list: ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:

 * This was working until the last update of backwpup. it appears this problem is
   not resolved and I can no longer back up these sites.

 * You can Download a mini Plugin from [http://marketpress.com/wp-content/uploads/2014/03/backwpup-disable-ssl-verify.zip](http://marketpress.com/wp-content/uploads/2014/03/backwpup-disable-ssl-verify.zip)
   with this activateed it will work again. It has to do with the cURL SSL Version.
   I will made a update in next time so that it works again without that Plugin.

 * Daniel, you might want to take a look at this commit in the Dropbox PHP library:
   [https://github.com/dropbox/dropbox-sdk-php/commit/05ad82740afd576073bfdb34136ef63d4174167e](https://github.com/dropbox/dropbox-sdk-php/commit/05ad82740afd576073bfdb34136ef63d4174167e)
   and make a similar change in your code (if it’s not already there).

 * It is possible to see this error with the “Reauthenticate” button on the dropbox
   tab and also demonstrate the fix works too

 * It’s been two weeks since you posted the hack solution. How many people are trusting
   BackWPUp to backup their WP and have no idea it’s broken?
 * When will the new fixed plugin be made available?

   is tested well.
