Brave Browser and Iris

Hello

Problem Setup:
Mopidy
Mopidy-Spotify
Iris frontend
Brave Browser

What is the error
Open Iris in brave-browser
go to Playlist open saved playlist from Spotify, and I just got the playlist picture and the spinning loading wheel.

Do same thing in Mullvad Browser at laptop and the playlist loads correctly.

Do the same thing in android phone with firefox and playlist loads as it should.

So is more my Brave-Browser that is faulty which is a little sad because I use Brave as my main browser.

Things I tried with:
Update brave - no solution
turning of Brave shields for mopidy server - no solution.
Checked brave console and got some wierd erros I dont understand. I post the below.
