#### What is the problem you are having with rclone? Copy one file (streaming via rcat) to azure blob container, autentication via sas token (blob container level) Same command works when using storageaccount-level sas token. A normal "rclone copy" command also works with container-level sas toke, so the issue seems to be specific to rcat. #### What is your rclone version (output from `rclone version`) 1.51.0 #### Which OS you are using and how many bits (eg Windows 7, 64 bit) debian buster (docker container) #### Which cloud storage system are you using?

Anything jump out @ncw? I'm definitely not a S3 guy 🙂 ---

It appears to be trying to create the container which isn't allowed with a container based sas. This is an easy fix though - we know we have a container already if we are using a SAS URL limited to a container so no need to create the container. I've merged a fix to [the latest beta](https://beta.rclone.org) - can you give that a go?

It works now! Thank you so much! Just another question: I see from the logs: "Azure container REDACTED: Target remote doesn't support streaming uploads, creating temporary local FS to spool file". Actually Azure blobs should support streaming uploads (some kind of streaming, at least), is it a feature that will be implemented in the future? Roberto ---

Glad it is working! Azureblob needs to know the size of the thing we are streaming in advance is what rclone is saying here. I had a brief glance at the code and it doesn't look like it actually uses the size, so maybe this is possible after all...

Strange! It works for me... Can you try this instead please?

This version actually works...I do not know if I used an incorrect version yesterday,sorry. By the way, that's great, thanks! Roberto ---
