Support » Plugin: UpdraftPlus WordPress Backup Plugin » Dropbox: "The request to link the app is invalid."

  • Resolved c77m


    New installation, unable to get Dropbox connected. I wiped settings to try again, and I get the same error. After wiping settings, I scroll down and select Dropbox as the remote storage. Hit Save Changes and then click the resulting link to authenticate.

    (The link is:, which then calls

    Clicking this link takes me to my Dropbox account and a red error appears at the top of the page stating “The request to link the app is invalid.”

    Reloading the UpdraftPlus settings page results in the message: “(You appear to be already authenticated).” But there is no app registered on Dropbox, and backups don’t work.

    After trying a manual backup, each page load tries to get the files backed up, to no avail:

  • As an additional note, this problem occurs on a client website hosted on Yahoo Small Business hosting. I installed and activated the plugin successfully just now on other sites at Bluehost and Dreamhost with no issues.

    I would not be surprised in the least if this is yet another problem with Yahoo hosting, but I’d like to be able to confirm that if not resolve the issue.

    From what you’ve said, I’d advise contacting Yahoo. They will be able to watch the network traffic back and forth between your site and Dropbox to say what’s going on. But from what you say, it sounds like you’ve got something in your hosting setup that prevents Dropbox from calling back in properly.
