### Server error logs

_No response_

### Additional information

This is likely because the file name contains characters that Nextcloud considers invalid: `feeder-export-2024-10-16T13:54:31.855.opml`.

When first saving the file locally to the SD Card and then uploading the file to Nextcloud from within Nextcloud ( + -> Upload files), Nextcloud renames the file to `feeder-export-2024-10-16T13_54_31.855.opml`.

Nextcloud should do the same (replace invalid characters automatically) when the file is being added via the DocumentsProvider.
