Reinstalled the client on my work computer, still can't play the album. It's just that album specifically, for me. It won't play anywhere: not on my phone, or in the web player, or on the desktop app. What gives?
The computer that I am having issues with has Sophos too. It seems to be a Sophos issue, not a Spotify issue.
From the thread you posted,
"In UTM 9.6, if the web server says that it supports range requests (Accept-Ranges: bytes) the UTM never changes the header. Therefore the client thinks that range request is supported. The client tries to do a range request and fails with 416. Some clients are ok with the range request failure and try again with a full file, some clients are not ok with it."
Good job @volleimer - I didn't think to look for an undocumented log file. Not impressed with Spotify support - all suggestions are the low hanging fruit - reboot your pc, delete some files, re-install the client. For more technical issues like there, they'res no support at all.
Spotify could fix their client to catch the 416 error and request the whole file, but Sophos should change the header in the UTM request to remove the option of the range-request. The Spotify client is just a re-branded web browser. If it was a proper app, this wouldn't be an issue.
Which of the above troubleshooting steps you tried
Reinstall the app. Three times.
Try a different network
Some songs don't play at all, others only play for 7 seconds at best. Spotify Connect doesn't work between mobile and desktop, but works just fine between my Android phone and iPad using the mobile app. Desktop app doesn't see new songs added to a playlist from the mobile app, and even if it does, it can't play them. Also can't use the web player (using Chrome, says "refused to connect", however it can open on the mobile version of Chrome, using "request desktop site"). Tried connecting via mobile hotspot and two different wi-fi networks but no luck.
Before this issue occured, the desktop app would sometimes not be able to play a song, but plays the next song just fine, and sometimes not show up, or can't be controlled by Spotify Connect. This issue has lasted for at least a week. Maybe two weeks, or three. Please solve this issue. Thanks.
