Произошла ошибка при чтении обработчика WSGI: Ошибка

когда я хочу открыть проект django, я сталкиваюсь с такой ошибкой. Мои проекты django живут на одном сервере, но я столкнулся с такой ошибкой на последнем сайте, который я открывал.

web.config:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
 <system.webServer>
  <handlers>
   <add name="Python FastCGI" path="*" verb="*" modules="FastCgiModule" scriptProcessor="c:\python39\python.exe|c:\python39\lib\site-packages\wfastcgi.py" resourceType="Unspecified" requireAccess="Script" />
 </handlers>    
 <tracing>
  <traceFailedRequests>
    <clear />
  </traceFailedRequests>
 </tracing>
</system.webServer>
<appSettings>
<add key="WSGI_HANDLER" value="umy.wsgi.application" />
<add key="DJANGO_SETTINGS_MODULE" value="umy.settings" />
<add key="PYTHONPATH" value="C:\Inetpub\vhosts\domain.com\httpdocs" />
</appSettings>
<system.web>
<compilation tempDirectory="C:\Inetpub\vhosts\domain.com\tmp" />
</system.web>
</configuration>

Ошибка, которую я получаю, заключается в следующем;

Error occurred while reading WSGI handler:
