Solution 4

C#

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..

You guys know what exactly happen when you use the above block of code, I think no. Using this you are exposing your data over TCP/Network and may allow your encrypted message to be read by an attacker. Thanks #Joshi MGR

Solution 1

Couldn't find enough information to get to the root of problem.

But check http://gathadams.com/category/google-maps/[^], and try to make a simple application to check if it works.

Solution 6

In my case I solved the problem by calling the web service by name instead of IP.

I just modified the host file (c:\Windows\System32\Drivers\etc\hosts)

for example I added new line to host file like (50.50.50.50 myservice-name.com.jo)
