Dropbox authentication error with UpdraftPlus from Wordpress

I have been using the Remote Storage option from within the UpdraftPlus plugin in Wordpress to keep backups on my dropbox account for several years. After moving my website to a new provider, the upload to dropbox stopped working. I checked that the connection to Dropbox is set up correctly by removing the settings for Dropbox and reauthentication. I can access and download from Dropbox old backups in the plugin without problems. But any attempt to upload files fails.

The following error is returned:

0020.397 (0) Dropbox: Attempt to upload: backup_2020-05-14-1059_MyWebsite_5b250aabb84c-plugins.zip to: backup_2020-05-14-1059_MyWebsite_5b250aabb84c-plugins.zip

0025.766 (0) Dropbox: chunked upload exception (Dropbox_BadRequestException):  (line: 225, file: /home/MyWebsite/wp-content/plugins/updraftplus/includes/Dropbox2/OAuth/Consumer/Curl.php)
0025.767 (0) An error condition has occurred for the first time during this job

It appears upload is started correctly and runs up to 100% but then does not complete or fails with some form of authentication. This problem occurs repeatedly and identically for every upload.

Thanks! That's helpful. It looks like you are getting an empty response body from the Dropbox API. We'll look into it.

You'll need to contact the developers of UpdraftPlus for assistance with this. Dropbox provides the API for third-party app access to Dropbox, but it's up to the developers that create those apps to support them. Dropbox cannot support third-party apps.

  The problem is an error that Dropbox returns as a result of a curl_exec call.
  
  I am only using the basic functionality of UpdraftPlus. There is no support provided for non-paying customers. I guess I am out of luck then and have to give up using Dropbox for this feature?

    miago The 'BadRequestException' seems to indicate you're getting a 400 error from the Dropbox API. Are you able to print out the response body itself? It generally should contain a more useful error message. Or, please let me know if the response body is actually empty. Thanks!
