I'm also encountering this issue with the warning " CapCut Pro APK HTTP Error 500.30 - ASP.NET Core app failed to start" after upgrading. It seems like the upgrade process triggered this error, and now my ASP.NET Core app is failing to start properly. I'm not sure what might be causing this issue or how to resolve it. If anyone has experienced a similar problem or has suggestions for troubleshooting, I'd greatly appreciate your assistance.
the error could be a connection string or two entries in the web.config if you have a Windows server. Comment out both entries. That helped me. this " <remove name="WebDAVModule" />" and " <remove name="WebDAV" />".
<modules> <!-- Remove WebDAV module so that we can make DELETE requests --> <remove name="WebDAVModule" /> </modules> <handlers> <!-- Remove WebDAV module so that we can make DELETE requests --> <remove name="WebDAV" /> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers>
