For various methods, such as web. if the user name and password configured in config are correct, or if windows Identity Authentication in IIS manager is enabled, try the following method.

(Note: If the IIS service of win10 Home edition control panel is not installed with windows identity authentication, you must upgrade the professional edition or above.

 

My solutions are as follows:
