Why Gradle can't download the dependency?

Began to take a course from emails.ru but got stuck

FAILURE: Build failed with an exception. 

* Where: 
Build file 'C:\_temp\OpenServer\domains\java\atom\build.gradle' line: 2 

* What went wrong: 
Error resolving plugin [id: 'org.springframework.boot', version: '1.5.8.RELEASE'] 
> Could not resolve all dependencies for configuration 'detachedConfiguration1'. 
 > Could not determine artifacts for org.springframework.boot:org.springframework.boot.gradle.plugin:1.5.8.RELEASE

Solution
In General, one of the addresses blocked by the RCN. But there is another address to work, it is necessary in hosts to register
52.7.23.178 repo.jfrog.org
address changes sometimes

Ask your provider why you can't get on jfrog.org. Or used VPN.
ISP said the address is blocked 34.202.204.251 . - nikita.Stracke commented on June 5th 19 at 21:20
