Thanks for the reply, it's actually using as AWS S3 object in NextCloud that I setted up my space as a primary storage : some tricky things about conf file in NextCloud 12.

I will soon write a tuto about using DO spaces as primary storage and integrate the answer that Jonleibowitz linked about linking them as external storages

I am having a problem configuring this as primary storage.

I discovered that by default with snaps the removable-media is not connected to the snap slot.

Run this command to check the status of your interfaces
snap interfaces nextcloud

Run this command to connect the Plug to the open slot:
snap connect nextcloud:removable-media

But I appear to still have some sort of routing/permissions issue.
