Unsupported or unrecognized SSL message

[aatomium]

Hello !
I've this problem when I try java -jar generatePins.jar 192.168.1.37:8888 sha-256 :

**Run this on a trusted network**
Generating SSL pins for: 192.168.1.37
##SSL pin set generator##
The generated pinset are base-64 encoded hashes (default SHA-1, but supports SHA-256). Note: only run this on a trusted network.

Usage: "java -jar generatePins.jar <host>[:port] hashAlgorthm" i.e scottyab.com:443 sha-256

Whoops something went wrong: Unsupported or unrecognized SSL message

What's the problem?
Thanks !
