Bug description
While trying to create a folder backed by backblaze S3 solution, nextcloud complains that the name is not DNS compatible.
I am following Backblaze instructions : https://www.backblaze.com/docs/cloud-storage-integrate-nextcloud-with-backblaze-b2
To do so, i've created a bucket like so :
named "rhebryn-archives", the endpoint is s3.us-west-004.backblazeb2.com
Yet, when trying to add the config as follow, nextcloud complains about an invalid dns name :
This may looks like a valid error, but there is no indication whatsoever on how to fix it

Can you enable debug log level (
log_level= 0) and check for log messaged forapp = objectstore?joshtrichards commentedon Mar 2, 2025
Are you certain there isn't a space at the end of the bucket name or something?
Check by running
occ files_external:list --output=json_prettymaybe?susnux commentedon Mar 2, 2025
Thats also my guess (and why I asked for the log)
Retidurc commentedon Mar 2, 2025
There was indeed a whitespace, but in the beginning of both the bucket name, and the domain name.
Trailing whitespaces where what I double checked first. And due to the wording of the error I was thinking about something more technical as the cause .
Should I mark this as resolved? Technically not a bug, but I think maaaaybe the error messages need to be a bit more explicit about leading or trailing whitespaces, just to not mislead about the real issue.

I agree.
Not everyone knows the acceptable characters for DNS hostnames off the top of their head. ;-)
And "DNS compatible" may be a bit too vague.
As for spaces, we could trim them I think safely automatically. We do that in many other places already.
