I'm also experiencing this.

Version: librespot 0.6.0-dev 2c425eb (Built on 2025-06-24, Build ID: EVBNJh5L, Profile: release)

When it happens the song being displayed in Spotify Desktop changes to the next in the queue, but the audio carries on unaffected beyond a minor blip in the audio. You also can't pause the song after this!

Second that. My country is "PL" (Poland), and on librespot 0.6.0 I'm experiencing the same issue. For me it's hit or miss - some songs play, some don't.

A couple of log lines with errors prior and after "parse CDN URL warning":

In the above case Remedy (feat. TS Graye) didn't play, but Adieu played fine.

Might be unrelated, but for songs that play fine I'm receiving 502 too:

Yes, I am experiencing connection closures and playback stops with the same error (spirc and connection issues). I don't think this is related to the CDN; it occurs randomly, every hour or every few hours. I am investigating; the connection might be lost. Perhaps "caching" the next streaming data can improve resilience or another retry pattern. I am new to the project and exploring the core; there may be many key points for this implementation that I am not noticing.
