EF PostgreSQL выдает "Полученное сообщение было неожиданным или плохо отформатировано" на Windows 8.

Я просто не могу найти причину, по которой EF PostgreSQL выдает исключение на Windows 8, но отлично работает на Windows 10. PostgreSQL размещен в IBM PostgreSQL Cloud и доступен с помощью защищенного соединения (SSL).

Строка подключения 

  <connectionStrings>
    <add name="DatabaseContext"
      connectionString="host=xxx.databases.appdomain.cloud;port=30308;database=ca;user id=admin;password=xxx;sslmode=Require;Trust Server Certificate=true;Timeout=100"
      providerName="Npgsql"/>
  </connectionStrings>

Сообщение об ошибке. 

An error occurred accessing the database. This usually means that the connection to the database failed. Check that the connection string is correct and that the appropriate DbContext constructor... -> A call to SSPI failed, see inner exception. -> The message received was unexpected or badly formatted.

ClassNameSystem.Data.Entity.Core.ProviderIncompatibleExceptionMessageAn error occurred accessing the database. This usually means that the connection to the database failed. Check that the connection string is correct and that the appropriate DbContext constructor is being used to specify it or find it in the application's config file. See http://go.microsoft.com/fwlink/?LinkId=386386 for information on DbContext and connections.
