External storage with Backblaze B2 - large file upload failing

Hi All,

I have recently installed AIO on an Ubuntu host running docker. Everything works fine, and I have external storage enabled with SMB and Backblaze as S3.

The SMB works fine, super fast and really consistent.

The Backblaze B2 is another story. I have mapped various buckets, without issue. However, when I try to upload file sizes circa > 500mb, it uploads fine, but then goes through a period of (what I assume) compiling, which fails.

I’ve increased Nextcloud memory to 2GB, to no avail. Max upload is 16GB and timeout is set to 3600.

Any ideas?

Thanks.
