Crystal Reports: Error connecting to SQL server - crystal-reports

Question

On our machine (Windows Server 2012R2), we have an ASP.net website that uses Crystal Reports (2008) for some reports. The database is SQL Server 2014. Here is the code related to the error:
ConnectionInfo cnnInfo = new ConnectionInfo();
cnnInfo.ServerName = serverName;
cnnInfo.DatabaseName = dbName;
cnnInfo.UserID = userId;
cnnInfo.Password = password;
ReportDocument rd = new ReportDocument();
rd.Load(rptUrl);
RptViewer.ReportSource = rd;
CrystalDecisions.CrystalReports.Engine.Database rptDb = rd.Database;
TableLogOnInfo tblLogOnInfo = new TableLogOnInfo();
foreach (CrystalDecisions.CrystalReports.Engine.Table tbl in rptDb.Tables)
{
tblLogOnInfo = tbl.LogOnInfo;
tblLogOnInfo.ConnectionInfo = cnnInfo;
tbl.ApplyLogOnInfo(tblLogOnInfo);
tbl.Location = tbl.Location.Substring(tbl.Location.LastIndexOf(".") + 1);
}
Here is the error that happens at this line:
tbl.Location = tbl.Location.Substring(tbl.Location.LastIndexOf(".") + 1);
Logon failed.

Note that the same database account is used to read the database and display info in the browser without any problem.
