In exploring Cardano wallets tutorial in the **Starting Cardano-wallet as a REST API server** section there is a mismatch in the port number.

```auto
cardano-wallet serve \
--port **1338** \
--testnet /home/user/cardano/testnet-byron-genesis.json \
--database /home/user/cardano/wallets/db \
--node-socket $CARDANO_NODE_SOCKET_PATH

```

&

```auto
curl --request GET \
  --url http://localhost: **1337** /v2/network/information | jq

```

Solution: Change 1337 with 1338
