Connect ASP.NET Core 3.1 with Interbase XE7 using FirebirdSql.Data.FirebirdClient (7.5.0) and Dapper

I am trying to connect ASP.NET Core 3.1 with an Interbase XE7 database. For the connection with the Interbase database, I'm using the FirebirdSql.Data.FirebirdClient (v7.5.0) Nuget package with Dapper.

The database connection string is:

"DefaultConnectionString": "Server=localhost;Database=127.0.0.1:\\TRAXDATA.IB;Uid=SYSDBA;Pwd=masterkey"

Dapper connection code :

using (var connection = new FbConnection(_config.GetConnectionString("DefaultConnectionString")))
{
    if (connection.State == ConnectionState.Closed)
    {
        connection.Open();
    }
}

Running this code results in an exception:

Looking at the internet for possible solution suggests changing firebird.conf file for

WireCrypt  
AuthServer 
AuthClient

properties but I did not install Firebird on my system.

Am I in right direction or missing something?
