Gradle sync failed: Connection refused

Question

So I just installed Android Studio again after a long time and it asked me to configure the proxy, so I did. I tested the connection and it worked.

Then it asked me

Answer 1

This happened to me when I updated Android Studio to the latest version.

The fix was to go to File/Settings/Build Execution Deployment/Gradle and check Use local gradle distribution

After that, in Gradle Home put the location to the gradle directory - in my case it was C:\Program Files\Android\Android Studio\gradle\gradle-3.2

Answer 2

I am writing on this old post as I have also faced the same problem after updating the Android Studio to 3.5. I was not using any proxy setting in my current project, still, it was showing me connection refused error. To resolve this problem I deleted the .android and .gradle file from User folder and restarted the android studio. It helped me to rebuild the project successfully.

Hope it will help you out.

Answer 3

For me it worked like this:

1. -turned off firewall and antivirus
2. -deleted .gradle file. location: C:\Users\user\.gradle
3. -restarted android studio
4. -checked internet connection

P.S. There is no proxy in my system (windows 8.1)

and it worked! hope this helps.

Answer 4

This worked for me

1. commented this lines in gradle properties

systemProp.https.proxyPort=41258 
systemProp.http.proxyHost=109.199.77.83
systemProp.https.proxyHost=109.199.77.83
systemProp.http.proxyPort=41258

2. use vpn
3. rebuild project

Answer 5

I solved my problem by putting the proxy options with http and https. Before it was just http and was giving error, after I added https, it worked.

Answer 6

I've searched everywhere for the answer spend 3 days and finely find the solution is to disable Avast in my case, so if you are too had an antivirus try it or make an exception for Android Studio.
