feat: Enhance UDPServer initialization in Connect method

Updated the `Connect` method in `GenericUdpServer.cs` to include error handling for hostname parsing. The method now attempts to create a `UDPServer` instance with specified parameters and falls back to default initialization if an error occurs. This improves flexibility and robustness in server setup.
