I am trying to embed a dashboard into my application, when I do local tests (localhost) it works correctly, when publishing to a domain I get an error on the screen where it says that quicksight refuse to connection. Has anyone experienced something similar? I already added the domains in the list …

Finally we solved it, there was a problem in the CORS configuration of helmet in the node server. app.use(helmet({ crossOriginEmbedderPolicy: false, }));
