fetchRemote times out for local data when the MTA server is bound to multiple ips

[Brophy]

Describe the bug

Using multiple comma-separated IPs in the <serverip> block causes fetchRemote to time out with Status Code 28 when used on local or LAN data.

This does not seem to be an issue when the <serverip> block is set to auto.

Steps to reproduce

1. Define multiple IPs in <serverip> block in mtaserver.conf
2. Use fetchRemote to get local HTTP data (not tested with https)

Version

MTA:SA Server, Linux, 1.6.0-9.23285.0

Additional context

The HTTP data is served by nginx
The call works using a command-line curl command on the same machine
