monrod.exe errors

I am running into two errors when issuing the command: `monerod.exe --zmq-pub tcp://127.0.0.1:18083`

> 2021-09-20 19:54:20.936 F Error starting server: Failed to bind IPv4 (set to required)
2021-09-20 19:54:20.948 E Exception in main! Failed to initialize p2p server.

Any suggestions on fixing this?
