I use s3cmd with exactly the same key/secret from same host to upload copies of sqlite file to S3. I do this once per day via cron.

forgot to add for the purpose of this report I changed my config to turn on debug logging:

access-key-id: redacted
secret-access-key: redacted

logging:
  level: debug # options: debug | info | warn | error

dbs:
  - path: /gotosocial/sqlite.db
    replica:
      url: s3://dustyninja-backup.sfo3.digitaloceanspaces.com/db

Already included my bucket name above so leaving it here now (it's fine - bucket is empty).

I was able to get working using v0.3.13. I tried v0.5.3 with exactly same config and still get error above.

I encountered the same issue when I upgraded to the latest version of Litestream. I am using a self-hosted instance of Minio as my S3 endpoint, and adding the new config option sign-payload: true seems to have solved the issue for me.

[plttn]

Thanks for listing the config option! Backblaze B2 now also requires sign-payload: true.

[mzmcgrat]

Maybe the documentation/examples for the various s3-compatible endpoints, and especially this table: https://litestream.io/reference/config/#s3-compatible-provider-requirements should be updated, since apparently both B2 and Minio require sign-payload: true now.

[MohamedBassem]

I wonder if this should get called out in the release notes. Because litestream was working fine without sign-payload: true on 0.5.2 and only after upgrading to 0.5.3 did it start failing (and it seems like a new config option anyway).

[jiqiren]

Thanks for all the comments everyone! I never saw the option sign-payload: true at all to know about it. This was my first experience / attempt to use litestream and it was pretty frustrating. Will be switching over to v0.5.3 and add in sign-payload: true.

[kalbasit]

I got hit with this as well using my MinIO instance; Adding sign-payload: true fixed my issue.
