    BackWPup Version ?

    Latest – 3.0.10



    @jetlej Quick update: we’re looking into it, stay tuned!



    Hi jetlej , coming back to your question. The authentication issue is likely to be caused by something interfering while BackWPup tries to connect to the other server in order to send its authentication request. That “something” can be a) a caching plugin, or b) the hosting company when it doesn’t allow for external connections other than to
    Do you run a caching plugin on your site?
    Who’s your webhost?

    I use W3 Total Cache. It’s definitely not my dedicated server on SoftLayer.

    But I know that W3TC does not cache any admin pages, could that still be the issue?

    Hi jetlej,

    we had some troubles with W3TC and our plugin. Please try to authenticate with dropbox when this plugin is disabled.


    Okay thank you!



    For the record, there are a couple of possible causes to this issue:

    • WordPress cannot make external requests (host resticitons)
    • A caching plugin caches transients, so BackWPup is served a wrong authcode or no authcode at all.
    • Another plugin may be interfering.
