Arch Linux + foobar2000: cannot connect to Internet?

[kellennnnss12]

wine version: wine-8.2
foobar2000 version: foobar2000 1.6.7 and foobar2000 v2.0 beta 24 [x86]

In the fb2k "Preferences: Components" page, the "Get updates" button returns "Could not check for updates: Network authentication error".
fb2k component "foo_uie_eslyric" is unable to download data.
fb2k component "foo_scrobble" is able to publish to last fm.

If I need to provide any logs, please tell me.

Partially solved and partially made worse:
Referring to https://github.com/PathOfBuildingCommun ... ssues/2885, I installed lib32-gnutls, which provides libgnutls.
- foo_uie_eslyric can now download data.
- foobar2000 crashes upon executing "Get updates", instead of presenting the previous error message.
