When I am using following code, which takes location name & returns latitude & longitude; Subgurim.Controles.GMap.geoCodeRequest(......) it is showing an error:

System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

How do I fix it?

Edited for Grammar, Syntax and Readability.
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;
//add following code before smtpClient.Send()

smtpClient.EnableSsl = true;
ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };

I think, SMTP for Gmail configuration it is not needed but for using local mail server it is very very important. Thanx a lot..
Couldn't find enough information to get to the root of problem.

But check[^], and try to make a simple application to check if it works.
