The external network connects to the remote desktop of the internal network host through the socks5 proxy enabled by the nps. It has been used well before. Since the upgrade of win11, it has been unable to connect. The error "This computer cannot connect to the remote computer. Please try to reconnect. If the problem persists, please contact the owner of the remote computer or the network administrator", "Error code: 0x904", "Extended error code: 0x7" is reported
