SDK manager Unknown host dl-ssl.google.com

Question

I am unable to update packages in SDK manager , it shows Download interrupted: Unknown Host dl-ssl.google.com. I am not using any proxy and my Comodo firewall is also turned off. I have also tried to run SDK with admin privileges. Anyone know how to solve this ? I have read many posts regarding this but nothing has worked so far.

Answer 1

The problem is surely antivirus. Comodo firewall runs in background even if you disable the firewall and that causes problem with SDK . I too had the same problem.

1.run comodo settings
2.defense+
3.list active processes
4.add adb.exe to trusted processes
5.restart server: run "adb kill-server" "adb start-server"

For Comodo 6.x

1.Open Comodo
2.Click Tasks Icon at right top
3.Click Advanced Tasks
4.Click Open Advanced Settings
5.Select Security Settings --> File Rating --> Trusted files from left panel
6.Click on the upward arrow icon at the bottom
7.Click Add --> add the adb.exe

Answer 2

Its because you are not able to connect to to the official Android repo using HTTPS protocol. Simply change it to HTTP under Windows -> Android SDK Manager.

Answer 3

Set the HTTP proxy settings in Android SDK Manager by navigating to: Tools -> Options. This resolved the issue for me.
