Successfully connects to wifi, But it doesn't work with tcp sockets for sending and receiving data.

I'm using this package for auto-connect to iot device. It gets connected successfully but when i wanted to receive data through tcp socket "SocketException: Connection failed (OS Error: Network is unreachable, errno = 101), address = 192.168.1.1, port = 5002". I face the above error whereas when i manually to wifi, i receive all the data through sockets.
