Getting help
In order to help you as efficiently (and quickly!) as possible, please fill in as much of the below requested information as you can.
Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can. 
The Basics
- Nextcloud Server version (e.g., 29.x.x):
- 32.0.0
- Operating system and version (e.g., Ubuntu 24.04):
- AlmaLinux 8.10
- Web server and version (e.g, Apache 2.4.25):
2.4.63
- Reverse proxy and version _(e.g. nginx 1.27.2)
replace me
- PHP version (e.g, 8.3):
8.3.22
- Is this the first time you’ve seen this error? (Yes / No):
Yes
- When did this problem seem to first start?
As soon as I attempted to connect to S3 buckets as external storage
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- Originally a softaculous install - years back
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
No
Summary of the issue you are facing:
Ran into UI limitation to attach external storage. It requires but will not validate admin’s password. This forces use of occ cli which has limitations and variance according to s3 vendor. But ultimately after solving for those issues, I was never able to get the s3 buckets to read/get/download or share files. But the volumes show up and I can move files onto the external storage buckets.
Steps to replicate it (hint: details matter!):
-
Go to Apps and install the external storage app
-
Configure an s3 bucket with bucket name, region, endpoint, key and application/secret key. Have done this with both Backblaze and Wasabi.
-
In administration settings, go to external storage and fill form. Don’t waste a lot of time here trying to get it right. Attempt to save your form edits. It requests password. Upon entering it errors: wrong password (bug - dead end)
-
Since UI doesn’t work, need to utilize occ command for occ file_external to set up the bucket access.
-
Sample occ syntax: php occ files_external:create \EXTERNAL amazons3 amazons3::accesskey -c bucket=bblaze-vol -c use_path_style=true -c region=us-east-005 -c hostname=s3.us-east-005.backblazeb2.com -c key=################### -c secret=#####################
-
Go back to Nextcloud UI. Storage should show up in the UI form for External Storage (administartion section) as well as in the External Storage option under personal settings. Viewing the form under admistration settings should indicate where an error is if one occurs. Ideally at this point, you have a new folder accessible from Files.
-
Copy (don’t move) a file from primary storage to the new external storage volume - or upload from local storage. It should move to the volume with no problem.
-
Attempt to open the file. It fails. Try to download the file. It fails.
-
Access the files from the s3 web UI skipping Nextcloud. The files are there, can be downloaded and are not corrupted.
-
Try to SHARE the file. There is no share icon. The share function is selectable in the UI, but as before, requires password that won’t validate. The CLI occ command of: php occ files_external:config [mount id #] enable_sharing “true”. And if one views the external_files:list, that mount reflects: enable_sharing “1” suggesting that this parameter was altered and set. BUT, there still is no sharing option once in files.

2 seemingly successfully installed s2 storage buckets.
No share option visible:
This is the external storage form that is not reflecting the CLI enable_sharing command.
All the other fields in this form were inserted via occ CLI, not in the web UI. The webUI requests password:
…and ALWAYS fails, despite a correct password.
