My WEP API hosted in kubernetes pods are unable to communicate to external IP

I am not able to connect my on prem SQLSERVER database from the kubernetes pods.(Bare metal) logs: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections

Tried connecting to my SQL SERVER from other applications hosted on IIS 
and was able to connect.

Code:

public class DBFactory
    {
        public static List<T> Fetch<T>(Expression<Func<T, bool>> predicate, out long totalRecords) where T : class
        {
            List<T> response = new List<T>();
            using (var db = new ProviderMasterConnection())
            {
                totalRecords = db.GetTable<T>().Where(predicate).Count();
                if (totalRecords > 0)
                    response = db.GetTable<T>().Where(predicate) .ToList();
            }
            return response;
        }

My pod is not able to communicate to outside IP I have kubernetes 1.14 and used weaver for cluster networking. Also I have used traefik as my ingress-controller.

Firewalls are all disabled so this can't be a firewall issue.
