ClickOnce Installation is not working for SingTel Internet Users

Hello,

I have deployed my project by using ClickOnce on my host. But I'm not able to install my project if I'm on SingTel connection. I have tested with StarHub connection and it was working fine.

Does anyone has any idea about this problem? Someone from MSDN forum is also facing the same problem like me. http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2871876&SiteID=1

Thanks in advance. 

Have you tried dropping an email to Singtel to ask what is the reason for this?

Have you tried the troubleshooting guide on the next page to the post you referred to?

What was the exact error? If you have a sample HelloWorld ClickOnce application for testing, maybe some of us here can test it out and suggest solutions or workarounds?

There are known differences in HTTP behavior for Singnet subscribers between the use of the transparent proxy farm versus the traditional proxy server proxy.singnet.com.sg:8080. For example, certain SSL sites (HTTPS) simply cannot have authentication cookies to be transmitted properly using the transparent proxies, and users are forced to explicit use proxy.singnet.com.sg before authentication can be successful.

I recommend trying both options and observe if there is any difference for your case.
