Description

This plugin uploads the validation challenge via SSH-FTP, also known as SFTP.

web.config

Optionally this plugin can place a web.config next to the validation file, to help IIS properly serve the response. There are many reasons why IIS can fail to properly serve the file. Some of them can be fixed this way. In interactive mode the program will ask you if you want to do this. In unattended mode you can request it using the command line. The web.config that will be copied lives in the root of the program directory with the name web_config.xml. You can modify it to fit your needs, e.g. for MVC sites you might need the following:

<configuration>
    <system.webServer>
        <staticContent>
            <clear/>
            <mimeMap fileExtension = ".*" mimeType="text/json" />
        </staticContent>
        <handlers>
            <clear />
            <add name="StaticFile" 
			path="*" 
			verb="*" 
			type="" 
			modules="StaticFileModule,
			         DefaultDocumentModule,
					 DirectoryListingModule" 
			scriptProcessor="" 
			resourceType="Either"
			requireAccess="Read" 
			allowPathInfo="false" 
			preCondition="" 
			responseBufferLimit="4194304" />
        </handlers>
    </system.webServer>
</configuration>

Or to disable URL Rewriting you might need to add this (in the beginning, right after <clear />).

<rule name="LetsEncrypt Rule" stopProcessing="true">
    <match url="^\.well-known.*$" />
    <action type="None" />
</rule>
