Using IQmol with Qchem server for education

On the IQmol website there is an option of using Qchem server for small jobs without having Qchem install on a local server.
I tried doing so using IQmol, but when trying to submit a job through the server, there was an error : “couldn’t connect to server”.

Am I missing anything ? Is it possible to use the server from outside the USA?
Thanks ,

There are no such restrictions of which I am aware, and the server does seem to be up and running as of right now. How is your server configured? I attach a screen capture of my configuration.
