Spring project template not showing templates

Question

I downloaded Spring STS 3.6.1 and I tried to create a spring MVC project, but the templates are missing:

As you can see it says requires downloading! I pressed Refresh several times and restarted STS, but I still can't get it to list the templates.

When I pressed configure templates:

I'm working on my home laptop running Windows 7. I'm able to access Eclipse market place and I'm not behind a proxy. I tried another laptop also running Windows 7, but in vain.

As user @AndrewEisenberg suggested here, viewing the Error Log gives me the errors as below

• Connection to https://raw.github.com/SpringSource/spring-integration-templates/master/si-sts-templates/builds/descriptor.xml failed on Connection to https://raw.github.com refused. Retry attempt 0 started
• Connection to https://raw.github.com/SpringSource/spring-data-gemfire-sts-templates/master/builds/descriptor.xml failed on Connection to https://raw.github.com refused. Retry attempt 0 started

So having a close look at the error in Error Log, by Windows - Show View - Other - Error Log, after calling File - New Project - Spring Project, I see the cause for this symptom.

It causes by the internet connection which cannot reach https://raw.github.com
