it does not seem like CORS problem, if you take a closer look at the browser logs, you'll see it says net::ERR_DISCONNECTED_INTERNET,

The net::ERR_DISCONNECTED_INTERNET error in JavaScript usually indicates that the browser has lost its connection to the internet. This error often occurs when trying to make network requests (e.g., using fetch, axios, or WebSocket) while the device is offline or there is a problem with the network.
