Object reference not set to an instance of an object (v2021)

[aspsteve]

I am getting the error message below when I upload my code to the server.

The code works perfectly well on my local machine.

An unhandled exception occurred while processing the request.

NullReferenceException: Object reference not set to an instance of an object.

AspNetMaker2021.Models.****+AdvancedSecurityBase.ValidateUser(LoginModel model, bool autologin, string provider) in AdvancedSecurityBase.cs, line 462

Make sure that you have published your application and set up IIS in your server correctly. Read the Publish setting in Generate Settings:
