I have just purchased a premium license and try to connect the webdav target IONOS Hidrive.
I get this error when testing the conncetion:
* PHP event: code E_USER_NOTICE: file not found: 403 (line 218, wp-content/plugins/updraftplus/includes/PEAR/HTTP/WebDAV/Client/Stream.php)
* PHP event: code E_WARNING: file_put_contents(webdavs://…@webdav.hidrive.ionos.com/……): failed to open stream: "HTTP_WebDAV_Client_Stream::stream_open" call failed (line 378, wp-content/plugins/updraftplus/methods/stream-base.php)
I have double checked my user and pw and I can connect to the webdav server with Transmit for example.
Any idea? I cannot check if there is a firewall or log at the webdav server. I think I need an app authorization feature in your updraft plus premium for IONOS hidrive.
