ERROR: Dropbox API: (59) Unknown cipher in list

I second this, no errors in over a year and then suddenly I am getting issues too.

Same problem here with two websites (hosted with two different companies). I will wait until problem is fixed to update on my other dozen websites.

Here is the log:

1. Try to send backup file to Dropbox …

I am experiencing the same problem. Not able to send backup to dropbox.

Dropbox API: (59) Unknown cipher in list:….

Please, any idea how to solve this problem?

See the other thread: [resolved] 3.1.2 broke Dropbox for me.
DANIEL HUSKEN has written a Mini Plugin to fix the issue.

You can try the follwoing mini Plugin to get it work again.

<?php
/**
 * Plugin Name: BackWPup disable SSL connection verifying

add_filter( 'backwpup_cacert_bundle', '__return_false' );

To install the mini plugin:

Copy the portion of code provided by Daniel in an empty text file, save it as backwpupsslfix.php and put it in /wp-content/plugins/ using an FTP client.

Then refresh the installed plugins page in WordPress and activate the plugin.

Hope this helps!

the mini-plugin helps and backups do work. (however, this solution is far away from being “clean” and “pretty”.)

I was able to use @wtankwey code to enable Dropbox authentication. During my backup test, Dropbox *immediately* didn’t like http instead of https. So I disabled his code, and ran the test backup again… but it failed after zipping all the files. Here is the log of the failure: http://pastebin.com/u3FpC2Y1

Has anyone been able to get Dropbox backups to work since yesterday with the newest version of this plugin?

OK, it worked after my first test. Maybe it just needed to get warmed up? I use OpenShift and sometimes it can be slow. That may have been the issue.
