Scaleway object storage

[French trad with google]
Hello,

I would like to be able to use the “Object Storage” storage space of Scaleway which is an Amazon S3 type service.

It seems that my configuration of Duplicati is good, but I have an error when testing “Failed to connect: A WebException with status NameResolutionFailure was thrown.”

Here is the config of Duplicati:
Use SSL: Yes
Storage type: S3 compatible
Server: custom URL (https://s3.fr-par.scw.cloud)
Bucket name: (bucket name)
Region: Custom region value (fr-par)
Storage class: Standard
Folder path: backup
AWS Access ID: (generated access key)
AWS Access Key: (generated secret key)
Client library to use: Amazon AWS SDK

Can you help me ?
Thank you.

Welcome to the forum!

For “Server” try taking off the “https://” part so it only has “s3.fr-par.scw.cloud”

Hello and thank you for your answer.
Unfortunately this now returns the error

Failed to connect: A WebException with status TrustFailure was thrown.

And if I disable SSL then I have the following error:

Failed to connect: The authorization header is malformed; the region ‘us-east-1’ is wrong; expecting ‘fr-par’

However, it is indeed “Custom region value (fr-par)” which is specified in my config

I try with the advanced option

s3-ext-authenticationregion = ‘fr-par’

and now it passes the connection test !
But it’s weird that you can’t enable SSL.

So the correct configuration to use this S3 storage is:

Use SSL: No
Storage type: S3 compatible
Server: custom URL (s3.fr-par.scw.cloud)
Bucket name: bucket name
Region: Custom region value (fr-par)
Storage class: Standard
Folder path: folder path
AWS Access ID: (generated access key)
AWS Access Key: (generated secret key)
Client library to use: Amazon AWS SDK
Advanced option [s3-ext-authenticationregion = ‘fr-par’]

Not using SSL seems kind of dangerous. While Duplicati data is encrypted, I’d assume your login isn’t.

Is said to be based on Ubuntu 18.04, which has a mono that doesn’t do modern TLS. What does mono --version say? If below version 5, you might also be heading for some obscure glitches with Duplcati.

Secure Socket Layer (SSL) / Transport Layer Security (TLS) has a test you can try, plus possible fixes.
