Cloud accounts · Other bucket storage (S3-compatible)
What does "Use path-style URLs" do, and should I turn it on?
Short answer: It changes how the bucket name appears in the address used to reach your storage. It's on by default for self-hosted and custom providers and off for Amazon. Turn it on if a self-hosted server won't connect.
It changes how the bucket name is put into the web address when Storage Studio talks to your storage. Most people never need to touch it: it's on by default for self-hosted and custom providers, and off for Amazon.
Turn it on if your S3-compatible server doesn't support the other style — a common case for self-hosted servers on your own network — and Test connection fails with the bucket name in the error. You'll find it under Advanced — addressing + transfer behaviour in the Bucket Storage form.
