More informations:

  • Nextcloud 33
  • This only happens when I add S3 storage; I tested it by simulating an FTP and it worked.

Exact same issue on my installation as well. Nextcloud 33 only when adding external S3 type storage (Dreamhost vps running Ubuntu, PHP 8.4, Apache 2.4)

Same problem here, running on a fresh AIO. Can’t add S3, error message looks just like above: “unknown error while checking password”.

Hi,

Exactly same error on fresh AIO too. Do you find a fix ?

6

Same problem. Seems like 33 broke S3 somehow, or we’re all just doing it wrong. By any chance, how many of us are trying to use backblaze? Just trying to figure out if there are any similarities other than us all running into the same issue.

Thanks,

B

I was able to mount S3 via occ command:

docker exec -it nextcloud-aio-nextcloud bash

./occ files_external:create "MOUNT_TITLE" amazons3 amazons3::accesskey -c bucket=BUCKET -c use_path_style=true -c region=REGION -c hostname=HOSTNAME -c key=KEYID -c secret=SECRETKEY

if successful, it will say (in green) “Storage created with id {x}”

take that ID number, then

./occ files_external:scan {ID#}

And everything seems to work.
