Android Studio gradle couldn't sync - android

I have upgraded android studio from 1.4 to 2.1 and my existing projects couldn't sync with the below gradle error
Error:Connection timed out: connect. If you are behind an HTTP proxy, please configure the proxy settings either in IDE or Gradle.
I am not using any proxy and I have made sure not to use proxy from the android studio IDE. but it keeps on coming with the same error and no idea how to fix this.
I am stack on this and would appreciate any one who could shade some light on this

Problem with my project on android studio

I am trying to edit a project on android studio, but I keep getting these errors:
Could not HEAD 'https://chartboostmobile.bintray.com/Chartboost/com/tapjoy/tapjoy-android-sdk/12.8.0/tapjoy-android-sdk-12.8.0.pom'.

Disable Gradle 'offline mode' and sync project
also it is telling me to upgrade Gradle version, the current version is 4.2.2

This is caused by bad net connect. You could download the sdk directly from the offical site and manually integrate it via referring to this guide.
also it telling me to upgrade gradle version the current version is 4.2.2
This is only a suggestion and not mandatory.

Android Studio Error : Unknown Host 'service.gradle.org'

I was working on a project on Android Studio 3.0 Beta 2 when suddenly i get the following error in my console:
Error:Unknown host 'service.gradle.org'. You may need to adjust the proxy settings in Gradle.
Enable Gradle 'offline mode' and sync project
Learn about configuring HTTP proxies in Gradle
I haven't made any changes to my gradle. I have tried invalidating caches and restarting Android Studio to no avail. I have restarted my computer as well but still no luck.
What's causing this to show up and how can i solve this?
I realized there was a typo and was supposed to be services.gradle.com instead of service.gradle.com. I don't know how this happened since the gradle-wrapper.properties file wasn't open but that was the issue.

Failed to import Gradle project error creating new project with Android Studio

Version of Android Studio:0.2.5 Build 130.782403, OS version: Windows 7 Pro 64bit, Java JRE/JDK version: 1.7, Android SDK V22.0.5, All updates/Extras are installed
I randomly get this error when trying to create a new project with Android Studio
Failed to import Gradle project: Network is unreachable: connect
Consult IDE log for more details (Help | Show Log)
It sometimes works when I'm not connected to the Internet
It sometimes doesn't work until I connect to the Internet
I believe the developer should be able to create a new project even if he/she doesn't have an Internet connection.
I had same issue with the latest Android Studio () today, and I finally found that configuring a https proxy for Gradle can solve the issue. I only set a http proxy at the beginning. Gradle needs to sync some files via HTTPS. Use IP address instead if hostname of proxy can't work.
In your android studio go to Help -> Show log in explorer then open the file idea.log and fetch in this file where is the problem, you gonna find where your android studio try to connect and it couldn't (proxy issues, some server link in your gradle refuse your connexion, non reachable server, no internet access...)
