Getting stuck in the fetching engine

After installing the https://github.com/d954mas/defold-utf8 plugin, it gets stuck in the fetching engine and gives the error Failed: java.net.SocketException: Connection reset after a few minutes.

What is the problem?

It seems like your editor has problems contacting the build server to build the native code in defold-utf8. Is this the first time you are building your project with a native extension? Can you access build.defold.com from a browser?

The problem is solved now. Thankful
