Multipart uploads aren't successful

[amang95]

I have seen this issue around Error: ETag does not match MD5 checksum being discussed on some PRs.
The above does not seem to be an issue when the object is uploaded as a single request.

But when an object size is large enough to require a multi-part upload, the process errors out with the above error in between uploading parts and hence the file isn't synced to S3 bucket.

For my instance, the file posing a problem is about 17.9 MB in size and fails to upload with the error:

S3 Sync: Syncing directories and S3 prefixes...
