bash-3.2$ granary client - rpc get /protocols 
Warning:

Hello,

@jeromesimeon : did you manage to solve this? I'm facing the same error, behind the hood it tries to connect to http://alphanet-node.tzscan.io:80/chains/main/blocks/head/protocols but this replies text/html instead of the data needed.

Any help?
