Issue

When entering a static SSH Host IP in config.json (ssh.host), this IP was ignored during HTTP requests (always tries to resolve whatever was behind '/host/'

Fix

Fixed by changing app/server/app.js and putting 'config.ssh.host' in front: when this is put at the default ("host:" null) in the config.json file, it will resolve whatever is after "/host/" in the URL:

Summary:

Potential fix below followed by opening http://localhost:2222/ssh/host/client will send you the IP address configured in json.conf.
