Unable to upload large files to R2 using Rclone

Copying files greater than ~5-10GB seems to trigger the below error consistently causing the upload to eventually fail after retries. Experimented with various chunk size settings but even with a standard copy command it will consistently fail after about 5GB into the upload.

Works with smaller files.

Command: rclone copy vzdump-qemu-103-2022_05_13-20_51_40.vma.zst r2:prox1-bk/test/1 -vv --stats=5s

I’ve rotated the keys multiple times to no avail.

I’m using the latest beta:
rclone v1.59.0-beta.6142.542c1616b
