'C# MySQL SSL Connection Error when trying to use conn.Open()

For the past 3 days now I have been struggling with an issue with MySQL connector in C#. Basically, I follow the MySQLConnector tutorial to open my connection in order to send data, but when I get to the MySQLConnection.Open() method, my code throws a SSL Connection error. Here is the code:

public async void SQLInsert()
        {
            string connStr = "Server=echstreme.de;User=c1Look;Database=c1Look;Port=3306;Password=redacted;";
            MySqlConnection conn = new MySqlConnection(connStr);

            try
            {
                await SendEmbedMessage("MySQL", "Attempting to connect to database");
                conn.Open();
                await SendEmbedMessage("MySQL", "Connection to Database Successful");
                MySqlCommand cmd = new MySqlCommand(sqlQuery, conn);

                cmd.ExecuteNonQuery();


                conn.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }

I have tried using both the Domain "echstreme.de" and the IP address, however both throw similar errors.

EDIT: THIS HAS BEEN FIXED Fix => "Server=echstreme.de;Port=3306;Database=c1Look;Uid=c1Look;Pwd=;SSL Mode =None";

Here is the complete error message for anyone needing it

Solution 1:[1]

If your host doesn't support SSL you can use SSL Mode options, None or Required.

Connection string must be like this

"Server=echstreme.de;User=c1Look;Database=c1Look;Port=3306;Password=redacted;SSL Mode=None"

When you go on mysql connection strings

You will see connection string with TCP port in it like this, try with this connection string construction:

Server=myServerAddress;Port=1234;Database=myDataBase;Uid=myUsername;Pwd=myPassword;

Also are you sure you are using right port?

you need change your drive connector to correct version of you database. if your use mysql 8 you need to use connector v8 and vice versa
