Filebeats plugin - failed to download out of all possible locations

Any idea what is causing the error below :

-> Installing logstash-input-beats...
Trying ...
ERROR: failed to download out of all possible locations..., use --verbose to get detailed information

Thought might have been a 2.1.0 issue, but tried it on 2.0.0 and it failed as well.

Can we see the full command you are running?

OK, seems to work without installing any plugins.

What I was trying to do was figure out why filebeats wasn't sending data. (no error) however it turned out for some reason in the logstash configuration if I remove SSL => true it works.

Warkolm was running :

./bin/plugin install logstash-input-beats

Now just have to figure out why SSL isn't working..
