Android Studio: Gradle project refresh failed - android-studio

I just installed Android Studio. I had to set the proxy to automatic for the installation to work. Now when I created a HelloWorld Project, I get the error:
Grade 'HelloWorld' project refesh failed
Error: Connection timed out: connect
From what I have read, it might be a problem with the firewall. However I don't have the rights to add exceptions to the firewall. So before I ask the IT-Support, I want to check if it could be anything else. Any ideas what I could do?

Try using the following link, but looks like you will need to contact IT as it clearly indicates the firewall issue.

Android Studio Gradle project refresh failed - Error host is down

I have tried many solutions to run Android Studio 2.3.3 on macOS 10.12 but this error still keeps showing and won't let me start a new project.
In the Event Log it says Gradle sync failed: Host is down. When I remove the gradle directories and invalidate caches it still has no effect.
Can anybody please suggest a way around this? All of the solutions I have seen posted in the forum haven't been successful so far.
Check your firewall settings to make sure it is not blocked. I have the same issue because I have blocked this with my firewall:
In my experience Android Studio requires an internet connection and unfettered access to the internet in order for you to develop anything. Hopefully this will improve with future versions.
There may be other ways to run the application without relying on Android Studio or gradle build process. One potential way might be to use the Unity platform. Otherwise you might try a google search for "build and run android app without gradle".

Sync gradle in android studio

I want to import library dependency in Android studio but I cant use in online Gradle mode .I didnt use proxy the http proxy is set to no proxy but whenever I sync the project it gives me error that if you are behind http proxy.... !!!
check your gradle.settings file and see if you set the proxy there. It automatically happens with a dialog when a new project is created or opened.

Error in Connecting to TFS with Visual Studio 2012

This is the error I get when I try to connect to TFS. The only change that I had made to Windows Live account was to enable "Two-Step verification".
Visual Studio isn't giving me an option to change the credentials in case I may have entered it wrong the first try I made to connect.
I was able to connect to TFS from another system.
Any help would be appreciated.
I was also encountering same error which is resolved after cleaning up cache.
Try after deleting cache from following location in your system :
C:\Users\gaurav1\AppData\Local\Microsoft\Team Foundation
make sure you close all visual studio instances before deleting cache.
Thanks,
Gaurav

Azure cloud service error in Development Fabric when I try to run in my Visual Studio

When I click the run button in Visual Studio, I stopped getting my solution to work. I checked the Development Fabric and in the status bar, I get the following error:
Failed to register logger for deployment
This is also strange because we the solution on SVN and my colleague has no problems at all. What does this mean?! And why did this start?
Damn it! I unloaded the worker role and did not update the cloud service project accordingly! It's solved now.
