您好，可能是你编写的web.config规则不正规，请核实

正确的规则如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>                
                <rule name="HTTP to HTTPS redirect" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions>
                        <add input="{HTTPS}" pattern="off" ignoreCase="true" />
                    </conditions>
                    <action type="Redirect" redirectType="Found" url="https://{HTTP_HOST}/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>
