(Likely) All Chromium based web browsers have an issue in version 64 - 66 causing the stream to die when it switches between main and fallback. Version 67 is confirmed to work again. However, that is currently the unstable branch. Check this link to find out when version 67 will hit stable. If you use Chrome and noticed the stream stopping relatively often (every few songs) sometime in the past week, that was likely me testing shit.

In the mean time, it is recommended you switch to some other method to listen to the stream. Either listen from a different browser, or use this to listen from your favourite media player.

This post will be removed when Chromium 67 hits stable.
