Hi~ @stefan.grasekamp ,
The FTP server that you are using is not common for NLST commands.
Typically, if the folder does not have a file, returns an empty list on the NLST request, but your server returns a 550 error.
This is scheduled to add to this issue to the next version.
Please use it after adding a file or folder to the root folder for the time being.
RaiDrive will only attempt NLST requests on the first FTP validation.
So, I’m wondering if the problem occurs with empty folders in the sub.
However, this can only be checked in the log file. After accessing the empty folder below, please send the log file(C:\ProgramData\OpenBoxLab\RaiDrive\log) by e-mail(support@raidrive.com).
And could you provide a test account and access information? If you provide a test account, it will be a great help in identifying issues and resolving issues.
If you can provide a test account, please e-mail(support@raidrive.com) us. We’ll check it out quickly and let you know again.
