Timeout exception in GetObjectInfo when path contains "[" or "]"
FTP OS: Unix
FTP Server: Synology FTP Server
Computer OS: Windows 10
I'm getting timeout exceptions when trying to GetObjectInfo of files containing "[" or "]" characters in path. When I'm trying to list directories named this way - GetListing returns empty array. Filezilla works fine with that.

I can confirm this also happens on PureFTPD server. If I do, for example:
var listing = await client.GetListingAsync()
listing contains all but paths/files containing '[' or ']'
