The WebException thrown shows no extra details in the InnerException and the StatusDescription comes back as an empty string. I've erased all program files on the microcontroller so I know storage space is not the issue and I don't think its a firewall issue since I can upload successfully through Filezilla. But when I run the code below I receive the error "The remote server returned an error: (451) Local error in processing." at the line "ftpstream.Close() " every single time no matter what file I try to upload, regardless of size or file type, and the new file does show up in Filezilla on the FiPy but with a size of 0 bytes. I can successfully upload program files via Filezilla. I just don't understand why LocalUser isn't working anymore.I'm writing a Windows Forms application in C# that allows a user to connect to a microcontroller and upload program files via FTP. So, I renamed the virtual directory on the FTP site from LocalUser to EDD_SERVER (the name of my server) and it worked like a charm. EDD_SERVER - and of course, that path didn't existed - Actually, procmon result was: "PATH NOT FOUND" -) It has to be THE EXACT SAME NAME as the server (Using Procmon I noticed that it was looking for a path called just the same as my Server -e.g. It doesn't use LocalUser as a wildcard for the local user accessing to the path. But apparently in IIS 10 / windows server 2019. In my case, when I set up all the virtual directories I created LocalUser folder (as it is written in all documentation about FTP isolation). What will guide you to the light is Procmon use it and you'll find whats going on. I'll share my learnings about this issue just if someone in the future hits again with "530 User cannot log in, Home directory inaccessible" on IIS 10 / Windows Server 2019 and everything seems to be well: And I don't know what could it be.Īny help would be highly appreciated, thank you in advance.ĭoesn't matter, I solved it using procmon. Looking at the docs it says that error # 3 is: "File system returned an error.". I've checked all the authorization rules and permissions and everything seems good.Ĭhecking the logs I found a detailed error code, the full code is 530 3 3. Also, the physical path has all the permissions for that user - IIS_USERS and IUSR too -, and the authorization rule allowing access)īut it doesn't work, FTP client always throws the 530 error (With: Home directory inaccessible). (I create the FTP Site, then LocalUser virtual directory and inside the folders named exactly the same as the user who will use them. And I created the FTP site (With user Isolation using virtual directories) As I use to do with these servers. I have a new VM instance in Google Cloud Platform running a Windows Server 2019 Datacenter OS with IIS 10. But now I'm facing this and I don't know how to proceed. In the past I've set up a lot of FTP servers on IIS with no major issues. I've been struggling with this issue for the whole week. ![]()
