I am using a SuiteCRM instance and and it says Access authorization is required and then returns a Invalid response, 418 message.

Without any http before the site name and with or without the www. I get invalid URL With http:\ I get Invalid response, 418 With https:\ I get Authorization is required then it disappears and I get Invalid response, 418

Also, the login button says loggin in ... and never stops. I already had to uninstall and reinstall once to get it back to login.
