Web Socket connection refuse with https

[silver mason]

Hiiiii, I have a problem with NestJS Web-Socket if i connect to this web socket in localhost it work normaly (http://localhost:3000) but if i deploy my app on my vps with https and domain name (https://api.discutoi.tonycava.dev/) i doesn't have response at my connection request on Postman but if for example on my front end i send a request to it he response properly and send the data to other chrome tab like a normal web socket and have this error once on my console :

I think it's because the first connection made is by "websocket" transport and the other by "polling" if some have already encountered this error please let me know

Hi mate in my case i remember just ignoring the error because in all case it work just fine, and it's so weird

My websocket configuration on the server :
https://github.com/tonycava/discution-app-back/blob/master/src/gateway/gateway.controller.ts

My websocket configuration on the client :
https://github.com/tonycava/discution-app-front/blob/main/src/lib/socket/webSocketClient.ts

Try copy and paste the config and see if it work for you (don't forget to change the server url or the CORS url)
