My connection string does not connect when using username and password - SQL (Urgent)

Hi

We have just replaced the server at a client and I am now trying to get my software to connect to the SQL database.

The connection string for the previous server was:

data source=MYSERVERNAME;initial catalog=dbHCA;persist security info=True;user id=myuser;password=mypassword;MultipleActiveResultSets=True;

This returns an error login failed for user 'myuser'.
Server authentication is set to both SQL and Windows

My user uses SQL server authentication and is mapped to dbHCA as a db_owner.
The properties look exactly the same as the previous server.

Am I missing something?

I did not setup the SQL server and we are using SQL server 2016.
Please let me know if you require more information.

As a side note: I can connect using integrated security
Data Source=MYSERVERNAME;Initial Catalog=dbHCA;Integrated Security=True

try to reset the password and use that new password in your connection string and try again?

The error message is still the same.
login failed for user 'myuser'.

I am connected to the new server.
I have written a quick programme to test connection strings to the server (see code below)

this connection string connects
Data Source=MYSERVERNAME;Initial Catalog=dbHCA;Integrated Security=True
which tells me that I can connect to the server using Windows Authentication

this connection string
data source=MYSERVERNAME\;initial catalog=dbHCA;persist security info=True;user id=myuser;password=mynewpassword;MultipleActiveResultSets=True;
gives me the error which tells me SQL authentication is not working.

  private void button1_Click(object sender, EventArgs e)
        {
            string txt = textBox1.Text.Trim();
            SqlConnection thisConnection = null;
            thisConnection = new SqlConnection(string.Format( txt));

            try
            {
                thisConnection.Open();
                MessageBox.Show("Connected");
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            textBox1.Text = "";
        }

Open in new window

Oh man...I've been working on this for hours.
Finally, I followed Microsoft's Mantra - 'If all else fails...reboot' and guess what.
It works now...I am unsure why it never worked in the first place but thanks for your input.

data source=MYSERVERNAME;initial catalog=dbHCA;persist security info=True;user id=myuser;password=mypassword;MultipleActiveResultSets=True;

I would remover "persist security info=True;" part.
