What does this error mean? I get a lot of them.

The other party cancelled the transfer for whatever reason.
For this case - your node likely in a severed long tail: when the customer downloads a file, their uplink requests 39 nodes and starts download in parallel. As soon as the first 29 nodes are finished - the remaining got canceled: uplink requires any 29 pieces from 80 to reconstruct the file.
Depending on in what moment this cancel is happened, the error could be different - broken pipe, variations of https://support.storj.io/hc/en-us/articles/360028695691-INFO-piecestore-upload-canceled, etc.

Ok thanks, I hope Storj will make some kind of simplified dignostics so people don’t need to actually use logs.
