I'm attempting to upload a large file (96GB) using dbxcli. So far twice it's failed with the following error:
Error: Post https://content.dropboxapi.com/2/files/upload_session/append_v2: read tcp [2600:<elided>]:50250->[2620:100:601c:14::a27d:60e]:443: read: connection reset by peer
 
The process exits with a code of 255. Retrying the command restarts from scratch. It's failed twice this way. I'm unsure if the issue is intermittent or repeatable. I'm unsure how much was uploaded before it failed (the progress indicator is overwritten by the error).
It would be nice if the implementation was resistant to this sort of error.
