EF PostgreSQL throws “The message received was unexpected or badly formatted” on Windows 8

[tomasr78]

I just can't find a reason why EF 6 PostgreSQL throws an exception on Windows 8 but works perfectly on Windows 10. The PostgreSQL hosted on IBM PostgreSQL Cloud and accessed using a secured connection(SSL).

The connection string

  <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>

The error message.

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.

Looking from full-stack trace I find that the exception related to SSL and last executed method is System.Net.Security.SslState.StartSendAuthResetSignal
