1. Configuration problem: Make sure that your ARM64 device is properly connected to the network and can communicate with the target server. Check network settings, firewall rules and routing configuration. To ensure that the port of WebSocket communication is not restricted or blocked.
2. Application configuration problem: Check the configuration file or code of WebSocket application to ensure that the connected target host and port number are correctly configured when deploying on ARM64. Make sure to use the correct IP address and port to establish WebSocket connection.
3. Application compatibility: Some WebSocket libraries and frameworks may have compatibility problems with specific hardware architectures. Check the documentation and support pages of the WebSocket libraries and frameworks you use to ensure that they support the ARM64 architecture. There is a compatibility problem, please try to update to the compatible version of ARM64, or find an alternative library and framework.
4. Hardware resource limitation: ARM64 devices have limited hardware resources, performance or quota restrictions, and cannot connect to WebSocket. Make sure your device has enough memory, processing power and network bandwidth to support WebSocket connection.
5. Server configuration problem: Check the configuration of WebSocket server to ensure that it correctly monitors and processes incoming WebSocket connection requests. Ensure that the WebSocket server is configured correctly and running.
