Need Help running Client and Server which are throwing errors/frozen.

[mithmnjrkr]

When running the client UI which is supposed to show the token it won't open anything & server with google Oauth constantly gives Unauthorized even though It has the correct authorization credentials.

I have added sample commands and configs used to run it.
Need help running this is there any simple manual I can refer to.
To open/view the token on UI I'm using this.

./cashier --ca "http://sshca.example.com:11000"

Config passed to the server in the below way

./cashierd -config_file cashier.conf
