[quote:3rz3jtce]CORS needs to be set up on the server you are requesting data from, not from the construct app or the domain hosting the construct app. It is set in the hosting server's configuration files.
Are you sure? Because when I disable cors locally on my browser, the data gets retrieved from the source successfully. This would indicate that the data provider is sending the message anyway and its my construct hosted server that is not able to receive it (or send the request) correctly.

no. but I put that there as an example
