Failed writing data to output stream

│Failed writing data to output stream

What could be causing this?
I'm streaming a collection of MP3 which are served by a virtual directory mounted by rclone from google drive.
Streaming works ok for the most part but sometimes I get the error and it skips track, continuing with the next in playlist.
