EF is not connecting to the correct server, why?

Question

Entity Framework

Hello, I have a project in which a local database was made using EF

Now I want to upload this database to the hosting, I took the connection string that was offered there and I got this

<connectionStrings>
    <add name="PostDataBase"
         connectionString="Data Source=SQL5101.site4now.net;Initial Catalog=*****;User Id=*****;Password=*****"
         providerName="System.Data.SqlClient"/>
  </connectionStrings>

all passwords and the rest are written correctly

When update-database -verbose writes this

Target database is: 'PostDataBase' (DataSource: (localdb)\mssqllocaldb, Provider: System.Data.SqlClient, Origin:

as I understand it, it takes not what I wrote, but what is above and because of this it does not work
