For digitalocean:
host: "(region). digitaloceanspaces.com:443 "
bucket: “(bucket name)”
key: “(key)”
secret: “(secret)”
multipart: false
secure: true
(verify commented out entirely)

So for you - make sure to add your creds that have the right scope (r/w), and try specifying the bucket .

Then in clearml tasks themselves you tell the task using output_uri=“s3://(region).digitaloceanspaces.com:443/clearml/”

(I import this as a constant from a _constants.py file across tasks)

This exact specific combination is what ive been using without an issue, but it took hours of guessing to get to it

i ran into this recently.
its a small thing but double check the port. should be 443, not 433 as in the docs (typo?) - seems you got this in the screenshot .
no region should be set .

i dont use backblaze but if it helps i can show my digitalocean spaces config . should be comparable .

Hi SmallTurkey79 could you please share how you did that? Here is how I tried, with 443 and no region, but still not working. The endpoint variable in clearml/storage/helper.py always returns None.
Thanks!

Try removing the region, it might be confusing it

Yes, i can get access with the boto3 client

Just to make sure, does Backblaze support the boto3 SDK?

Great, SmallTurkey79 I will check that and let you know! Appreciate that!

Hi CostlyOstrich36 I tried, but got
2025-01-15 16:35:13,846 - clearml.storage - ERROR - Failed uploading: An error occurred (InvalidAccessKeyId) when calling the PutObject operation: The AWS Access Key Id you provided does not exist in our records.

and I saw that endpoint_url is None. Indeed cfg.host is returning None.
I tried to hardcode the endpoint_url and got
2025-01-15 16:37:01,713 - clearml.storage - ERROR - Failed uploading: An error occurred (405) when calling the PutObject operation: Method Not Allowed
ValueError: Insufficient permissions (delete failed) for None

But I am still not sure if it is the about permissions because it was appearing the same ValueError before.

S3BucketConfig(bucket='mkrs-data', subdir='', host='',...)
in all cases i get that host=''.

Hi CostlyOstrich36 thanks! Yes, i did that like attached. I tried host: s3.us-west-004.backblazeb2.com , backblazeb2.com , with port :9000, :433.
and the log error is:
2025-01-15 13:01:58,264 - clearml.storage - ERROR - Failed uploading: Could not connect to the endpoint URL: " None "

it is trying to sue amazonaws still. Any hints on that?
Thanks!

Thanks SmallTurkey79 ! That actually solved my issue indeed!! Thanks!

Hi UpsetPanda50 , none AWS s3 solutions are also supported. Please see docs - None
