So, I’m using FTP server (integrated in IIS) on windows server 2019. The problem is FTP in IIS gives “550 File not Found”, without concluding what is the reason behind it. How can I find out what is happening? Thank you for your input in advance!
Firstly, let’s get a quick idea on the FTP 550 error.
The 5xx error falls under the permanent negative completion reply status of the FTP server. And, it means that the FTP server did not accept the command and the requested action did not take place. Further more, x5x error denotes File system errors in FTP server.
