UserManager and SignInManager not run correctly

my asp project run well when try to debug my asp project and connect it with its database , its Database is placed on godaddy Server .

//In this case I connect my project with external database on Godaddy Hosting
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
//Here it is return success as a result
var userID = UserManager.FindByName(model.userName)?.Id;
//Here it is return this '882ffec2-a71d-49d2-986d-4c7ee472dd8a' as UserId

but not run well when try to connect my asp project with local database that placed on SQL Server in my muchine,

//In this case I connect my project with internal database on local SQL Server on the same computer .
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
//Here it is return Failure as a result
var userID = UserManager.FindByName(model.userName)?.Id;
//Here it is return null value as UserId

Note One - Two Databases has the same schama and Data because I Create the local Database from script of the external database. I Generate the Script of Schama and Data.

Note Two - I am using Database First Approach

Oops, my problem is very simple, I have two different connection strings, the identityUser use first one connection string and the Entity Framework use the second one connection string.
my problem i was edit the second connection string to make it connect with local Database while the first connection string still connect to the external Database ,
now I fixed this problem when connect the IdentityUser and Entity Framework with single connection string
