RaspberryPi/IPv6 connect ECONNREFUSED ::1:3000

[HeartofPhos]

Using an RaspberyPi 4 with Raspbian GNU/Linux 11 (bullseye) all local Api calls done using IPv6 fail with the exception connect ECONNREFUSED ::1:3000 calls using IPv4 work as expected. The issue manifests when localhost resolves to ::1 when passed to axios as a url e.g. src/db/scanner.js:119

Reproduction steps

• flash a clean installation of raspbian to Rpi4
• install dependencies (node-js/git)
• clone and run mStream
• add a folder containing music from the web-ui
• observe console logs indicating exceptions during the scanner flow

Possible fixes

• Updating the json config with "address": "::" completely resolves the issue and maintains expected functionality for both IPv4/6
• Likewise directly updating src/state/config.js:56 to default the address configuration to :: also resolves the issue

After applying either of the above fixes, it appears to run without any additional configuration or issues.
