WinSCP Error: 405 Method Not Allowed

Troubleshooting WebDAV Access

Introduction

Users may encounter a 405 Method Not Allowed error when attempting to access files via WebDAV using WinSCP. This error message indicates a mismatch between the HTTP method used by the client (WinSCP) and the allowed methods on the server.

HTTP 405 Error

The HTTP 405 Method Not Allowed error occurs when a client sends an HTTP request using a method that is not supported by the server for the requested resource. In the case of WinSCP, this error may occur when accessing files via WebDAV using the incorrect HTTP method.

Troubleshooting Steps

1. Verify WebDAV Support: Ensure that WebDAV is enabled on the server and configured correctly.
2. Check HTTP Methods: Confirm that WinSCP is using the correct HTTP method for the desired operation. WebDAV typically uses the PUT, DELETE, and PROPFIND methods for file management.
3. Enable SSL/TLS: If the server requires SSL/TLS encryption, configure WinSCP to use it.
4. Check Server Configuration: Ensure that the server's firewall or other security settings are not blocking the HTTP methods used by WinSCP.
5. Contact Server Administrator: If all else fails, reach out to the server administrator for further assistance.
