Unknown interface for IP Address not 127.0.0.1

[Pinwheeler]

Description

as in #6 but the discussion around that suggests that it's only for localhost

Steps to reproduce

Steps to reproduce the behavior:

1. Using iPhone simulator
2. Connect to an IP address

import TcpSocket from 'react-native-tcp-socket'
this.client = TcpSocket.createConnection({port, host})

Current behavior

The socket fails to connect with error
Unknown interface. Specify valid interface by name (e.g. "en1") or IP address.

Expected behavior

The socket should connect

Relevant information

OS	iOS
react-native	0.61.5
react-native-tcp-socket	^3.2.3

@Pinwheeler, could you provide the host and port you are using to create the connection, please?

Here's my logging info around it.

 LOG  <Socket port: 9876 host: 167.99.166.69>
 LOG  [Socket - ERROR:: Unknown interface. Specify valid interface by name (e.g. "en1") or IP address.]

Ah... is this because that IP address is IPv6? Dang- do you know how to convert them?

[Rapsssito]

167.99.166.69 is an IPv4 address. There should not be an issue with that.

You can't convert all IPv6 addresses to IPv4 - there are more IPv6 addresses than there are IPv4 addresses.

@Pinwheeler, it is indeed a bug with the localAddress handling on the iOS part when connecting without specifying one. Thanks for the feedback! I will update when a fix is ready.

@Pinwheeler, I have released a fix version (3.2.7). Could you please test if the issue persists using that version?

[Pinwheeler]

Checked using the latest version and the issue is resolved. Thanks again!

Glad it worked!
