Token Expired

I’ve got this error when i try to upload to dropbox:

[13-Jan-2022 16:26:13] /home/ansiaviajera/web/ansiaviajera.com/public_html/wp-content/plugins/backwpup/src/Http/Client/WpHttpClient.php: DropBox API: cURL error 28: Operation timed out after 5000 milliseconds with 0 out of -1 bytes received
[13-Jan-2022 16:26:14] 3. Intenta enviar el archivo de copia de seguridad a Dropbox …
[13-Jan-2022 16:26:14] El token ha caducado; se ha obtenido un nuevo token (***The token has expired; a new token has been obtained)

I’ve got the SAME configuration with this plugins on more domains on the same server and they work properly. Tried to reconnect to Dropbox and generate new token (several times) and still happens

Any help? y really want to use this plugin
