I have a problem, Help me
Mixed Content: The page at 'https://expzero.com/todolist/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://54.88.59.233:3000/websocket'. This request has been blocked; this endpoint must be available over WSS.
I have a proxy that has the SSL certificate, the proxy sends the requests to an application and that application connects to a backend that has the address shown in the error 'ws: //54.88.59.233: 3000 / websocket'.
