Netbeans update fail

Question

I have no problem in my internet connection. But getting every time this screen when I try to update netbeans plugins or IDE itself.

Answer 1

Are you using Firewalls? May be its blocked by your firewall,

try to check the blocked applications.

Update

probably yes, because Kaspersky most of time will block without notice or accidentally might be blocked. so better try to check blocked application lists in kasperksy. Check this links might help you to solve:
