unsuccessful installation on kibana 6.4.2

[sp1thas]

I'm trying to install this plugin on Kibana 6.4.2 but I'm getting the following error:

./kibana/bin/kibana-plugin install kibana-iframe-communicator-plugin-1.0.1.zip 
Attempting to transfer from kibana-iframe-communicator-plugin-1.0.1.zip
Attempting to transfer from https://artifacts.elastic.co/downloads/kibana-plugins/kibana-iframe-communicator-plugin-1.0.1.zip/kibana-iframe-communicator-plugin-1.0.1.zip-6.4.2.zip
Plugin installation was unsuccessful due to error "No valid url specified."

Have you any idea how to bypass this error?
