WebSocket connection failed with Socket.IO

[AdrianoLuiz]

Wappler 5.8.2
Server Linux CentOs7

I am encountering an issue with establishing a WebSocket connection using Socket.IO. I have been trying to connect to my Socket.IO server, but I keep receiving the following error:

websocket.js:43 WebSocket connection to 'wss://arrematemotors.com.br/socket.io/?EIO=4&transport=websocket' failed:

I have verified that the Socket.IO server is running correctly and listening on the correct port. I have also ensured that the SSL certificate is properly configured for HTTPS. However, I am still unable to establish the connection.

Obs. I would like to inform you that I am not using Docker or Redis in my environment.
