Can't play music over HTTPS and VLC output looks similar?
[0x83916dc] gnutls tls client error: TLS session: access denied [0x83916dc] gnutls tls client error: Certificate could not be verified [0x83916dc] gnutls tls client error: Certificate's signer was not found [0x83916dc] main tls client error: TLS client session handshake error
Solution is very simple - feed VLC with Firefox certificates.
On Arch Linux you need to execute just one command:
$ cat /usr/share/ca-certificates/mozilla/* > ~/.local/share/vlc/ssl/certs/ca-certifcates.crt
