CORS policy rejection when connecting to Clay testnet from browser

Hi folks, I’m getting a cors rejection error when attempting to connect a user’s wallet via @self.id/framework and useViewerConnection.

This error did not occur a few weeks ago when testing my application.

If anyone has any suggestions I’d greatly appreciate it!
