S3 Host / Endpoint not shown when using a custom service

[severo]

I use the Scaleway S3 service, which is compatible with Amazon S3 protocol (everything works as expected), but there is a small bug.

I configured the host that way:

But when I come back to the backup configuration page, the field is empty, while I expected to see it filled with s3.fr-par.scw.cloud:

@severo What did you enter as 'S3 Path`? I can't get it to work.

hostname 'box.emeel.net.backup.s3.nl-ams.scw.cloud' doesn't match either of '*.s3-website.nl-ams.scw.cloud', '*.s3.nl-ams.scw.cloud', 's3-website.nl-ams.scw.cloud', 's3.nl-ams.scw.cloud'

Ah, dots in the S3 Path do not work.
