Cover art uploading problems; '⚠ Error uploading image' and a stuck uploading process

[jesus2099]

There is a CAA status page, with a red line indicator; For next time you are wondering about its recent availability:

Random " Error uploading image"

For future reference, here you can check the status of the Cover Art Archives server. If you see a red line in the top-left graph, the server is experiencing difficulties. The only thing you can do in that case is wait until it is fixed.
