UDP failure: The system detected an invalid pointer address in attempting to use a pointer argument in a call. (OS error 10014), client cannot connect remotely.

The server-side system is win server 2012, the software is 1.14 (it was 1.12), the id_ed25519 is configured, and rustdesk-utils.toml is configured (the content is [options] relay-server = "192.168.0.111:21116"), and there are two months in the period set to ([options] relay-server = " xxx.com:21116"), under such a configuration, it has been used normally for two months, and now after the domain name expires, when the domain name is changed and reconfigured, it is found that the client cannot connect to the server, at this time, the server can be pinged, and SMB access can be normal, but the client prompts, "the remote computer is offline", and the client is now 1.3.9, which was originally 1.3.7. The server now always prompts "ERROR [src\rendezvous_server.rs:255] udp failure: The system has detected an invalid pointer address when trying to use a pointer parameter in a call. (os error 10014)", but I'm using netstat -ano| The findstr "21116" test is normal, how can I solve it?

Start with the UDP error reported at src\rendezvous_server.rs:255 and review how the rendezvous server handles UDP on Windows Server 2012. Reproduce the failure using the reported relay-server configuration and port 21116, comparing the changed domain setup with the working state. Done means identifying the cause of OS error 10014 and confirming that remote clients can connect again.
