unable to configure S3 scaleway backend

[Benance]

System Info

• PHP Version: 8.1
• XBackBone Version: 3.7.0
• Webserver: Apache
• Database backend: Mysql

Describe the bug
I try to install xbackbone on a web hosting at planet hoster (world lite) with an S3 object storage backend at scaleway
After filling all the infos and click on "install" button, I get an error:
Storage setup error: Error executing "ListObjectsV2" on "https://drop.s3.fr-par.scw.cloud/?list-type=2&prefix=storage_test.txt%2F&max-keys=1"; AWS HTTP error: cURL error 7: (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://drop.s3.fr-par.scw.cloud/?list-type=2&prefix=storage_test.txt%2F&max-keys=1 [0]
I've looked at the curl error and it seems that xbackbone is unable to connect. my access key and my secret are the right one (since I can connect this bucket to nextcloud with the same credentials for example)

To Reproduce
Steps to reproduce the behavior:

1. create a bucket on scaleway objet storage
2. fill in the fields in the xbackbone web installer with the infos about the bucket
3. Click on the "install" button
4. See error

Expected behavior
installation successful
