@<1523701087100473344:profile|SuccessfulKoala55> Thanks!
After some research this config works:
s3 {
key: "<AWS_ACCESS_KEY_ID>"
secret: "<AWS_SECRET_ACCESS_KEY>"
region: "auto"
use_credentials_chain: true
credentials: [
# specifies key/secret credentials to use when handling s3 urls (read or write)
{
host: "<id>. r2.cloudflarestorage.com "
bucket: "<bucket_name>"
key: "<AWS_ACCESS_KEY_ID>"
secret: "<AWS_SECRET_ACCESS_KEY>"
multipart: false
secure: true
}
]
}

And output_uri in this format “s3://<id>. r2.cloudflarestorage.com/ <bucket_name>”

Hi @<1554638179657584640:profile|GlamorousParrot83> , how did you set up your clearml.conf file? Can you share?

@<1554638179657584640:profile|GlamorousParrot83> , can you add also the full log?

@<1554638179657584640:profile|GlamorousParrot83> the URL to the server should start with s3:// and not http, it should also include the port number (443 is case of a secure url)
