On Tencent cloud Server to do. I used 0.0.0.0 to bind the listening port, and an error occurred when running. If I use the ip found in localhost or ifconfig, there will be no error. Because ifconfig contains the intranet address. I want it to be accessible from the public network.
The following is the log where the error occurred：
E |2023-09-15 17:19:37 1694769577143334| [oatpp::network::tcp::server::ConnectionProvider::instantiateServer()]:Error. Couldn't bind. Cannot assign requested address
terminate called after throwing an instance of 'std::runtime_error'
what(): [oatpp::network::tcp::server::ConnectionProvider::instantiateServer()]: Error. Couldn't bind Cannot assign requested address
