Socket Error on Search (It appears the issue is with the invidious API)

[ifndefJOSH]

Hey, just downloaded your app from F-Droid, but I ran into a small issue, described below:

Bug Description: Upon downloading version 2.2.0 from F-Droid I attempted to search for an artist and got the following Dart exception:

Exception: SocketException: OS Error: Connection refused, errno=111, address=invidious.13ad.de, port=42568

It appears this is the URL from one of the web APIs you are using, as referenced in main.dart:50

var brightness = ValueNotifier("dark");
var invidiosAPI = ValueNotifier("https://invidious.13ad.de/");
var quality = ValueNotifier("best");

I cannot find 13ad.de on the list of available instances on Invidious' website, and public whois data for 13ad.de gives me the following:

Admittedly, this raises a couple of red flags regarding this particular instance of Invidious. Perhaps you could use one of the other public instances or even host your own?

Others appear to have faced a similar issue (see issue #143 )

There is a setting to change the target invidious API. I changed, reloaded, and everything is working.
