Failed reading packet! Failed to receive packet

This function usually errors out with "Failed fetching audio key!" when getting API rate limited. "Failed reading packet!" is something different and new. About how many songs did you download before this appeared? Were you using the anti-rate limit config advice from the FAQ?

TypeError: unsupported operand type(s) for -: 'str' and 'int'

This second-depth error should be fixed with f9c9196. This should let you keep downloading more tracks if the primary error occurs again. Please do more large-scale downloads and see if the error occurs multiple times in a row across multiple tracks.

I also got the same "Failed reading packet! Failed to receive packet" error during a bulk download.
I had several successful downloads, then the error happened for one song, and then it continued to successfully download more songs.

I have DOWNLOAD_REAL_TIME set to true so maybe it isn't a rate limit issue 🤔. Its not a big deal though, Ill be able to retry all the failed downloads after the bulk download is done now that you have it skip and continue 👌

Ill lookout to see if it starts happening multiple times in a row. I will also start using --debug

I saw the error message again, but this time the song successfully downloaded and didnt give a error/stack trace.

I copied this output mid download:

[∙∙∙] Preparing download...

Failed reading packet! Failed to receive packet

and then the download completed and the output now looks like this:

I see "Failed r" looks like the error message was overwritten a bit.

The song I downloaded plays fine and is complete and has all its metadata correct 🤔

This may mean the alert is just a nuisance alarm. Probably caused by an unstable connection, but the missing/dropped packets/connection can be requested again. I can mute the underlying logger to stop the popups (see 443ddb5). If you find that one of the songs has been corrupted, please reopen this issue.
