Hi All - I’m getting a CORS error the moment I call the login() on lock: Access to XMLHttpRequest at ‘[https://fotonovelty-test.auth0.com/user/ssodata](https://fotonovelty-test.auth0.com/user/ssodata)’ from origin ‘[http://2018.wellplanned.events](http://2018.wellplanned.events)’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Even though my client settings list the calling domain in cors allowed origins. ![2019-03-25%2013_41_07-Window](https://global.discourse-cdn.com/auth0/original/2X/f/fa4b88f85e3ad59dbe29ae109e6d67afa989c10d.png) ![2019-03-25%2013_41_40-Window](https://global.discourse-cdn.com/auth0/original/2X/b/b0465c5d4f55052e82aede241389726c60b3e50e.png) Any help greatly appreciated! ---

Hey there! Can you share a bit more context around what you’re trying to build and what blocks you use for doing to? ---
