[AC-1562] Can login to online platform, but cannot login using appc CLI terminal

I'm having an issue where I can login fine to the platform.appcelerator.com portal, but I cannot login using the same credentials in the CLI or appC studio app. I've tried completely uninstalling and re-installing titanium (including node), and I am getting the same issue. I'm at my wits end, please help!. Here is my output from running this command: appc login -l trace __command__ search paths: [ "/Users/eric/.appcelerator/install/5.1.0/package", "/Users/eric/.appcelerator/install/5.1.0/package/node_modules", "/Users/eric/Desktop/projects/titanium/timer/plugins", "/Users/eric/Desktop/projects/titanium/timer/node_modules", "/Users/eric/Desktop/projects/titanium/node_modules", "/Users/eric/Desktop/projects/node_modules", "/Users/eric/Desktop/node_modules", "/Users/eric/node_modules", "/Users/node_modules", "/node_modules", "/Users/eric/.appcelerator/.npm/lib/node_modules" ] [PLUGIN-LOAD] 0ms /Users/eric/.appcelerator/install/5.1.0/package/appc.js [PLUGIN-LOAD] 570ms /Users/eric/.appcelerator/install/5.1.0/package/node_modules/appc-cli-titanium/appc.js [PLUGIN-LOAD] 0ms /Users/eric/.appcelerator/install/5.1.0/package/node_modules/arrow/appc.js log level set to "trace" executing command "login" set environment to {"registry":"https://software-preprod.cloud.appctest.com","security":"https://security-preprod.cloud.appctest.com","baseurl":"https://360-preprod.cloud.appctest.com"} noPlugins set for command "login" executing command "login" with no plugins
