Hi. Hope you're having a good day. Unfortunately, you seem to have missed a few important steps in the bug report form. Please update your report (you can edit it) or we'll be unable to look into this issue.

Hello,
thank you for your answer!

> you seem to have missed a few important steps in the bug report form

What field are additional necessary? The field "Configuration report"?
My nextcloud instance is running by my hoster and I have not access to the CLI via SSH. So I send the command "sudo -u www-data php occ config:list system
php occ config:list system
./occ config:list system" to my hoster with the request to execute the command and send me the result again.
Regards Michael

That and...

  • The nextcloud.log entries during these transactions (they will explain the specific reason for this error you're experiencing)
  • The verification check to make sure the code base is unmodified and uncorrupted
  • Probably/possibly some other things when we start to try to isolate the issue

If you're not the administrator of this Nextcloud installation, perhaps this is an Issue you should bring to your administrator/managed hosting provider first?

It's going to be nearly impossible to assist you (and for you to help us in doing so) without access to the configuration and logs (as well as, likely, the ability to change the config).

This channel is for reporting software bugs, not seeking technical support on general configuration issues or installation matters. I'd point you to the Help Forum, but even there they're going to expect the same details about your Nextcloud instance. :-)

Hello,

now I have insert the "Configuration report".
The log files will be submitted shortly afterwards.

Run also a occ files:scan first in case the oc_filecache is not up-to-date.

Also this.

Unfortunately currently there is no logfile
but I made some other tests

error occurs every time if I copy or transfer a file (docx, jpeg,...) from my local client (using file explorer) to another folder, which is connected via WebDav with NextCloud (using file explorer as well).
Target folder is located on my NAS connected via app 'External Storage Support'. Method: sftp

Looking at the file directly in NAS --> everything is fine

After several tests: it seems to me, that size metadata is missing (get lost) BUT the 'External Storage Support' app probably needs this information to process the file correctly

Hello,

I have same problem - only difference: hoster is 'Ionos' (Germany)

Thanks, Thomas

@ThomasHTT Do you have any log entries to add to the report? Without logs from either you or the original submitter we're kind of flying blind here. :)

Hello,

now I have update my nextcloud instance to 27.0.1 and I get the same wrong behavior.

(1) Store a file (e.g. docx) via nextcloud WebDav to the external storage NAS => the file have 13 KB

grafik

(2) Refresh the file explorer => the file have 0 KB

grafik

(3) Open Browser => the document is a file

grafik

(4) Download the file
(5) Refresh browser => file is a folder and corrupt

grafik

(6) In my NAS the file is still a file

grafik

And there are no server log with error in it, but I can 100% reproduce the error.

What else can I query from the system so you can investigate the error?

Thank you!
Michael

Not gonna lie, this looks like a ssh configuration issue or something.
I'm not familiar with Synology, but could you try another of their remote storage protocol like NFS or SMB and see if the behaviour remains ?

May be fixed by #40459 (testing welcome).

No sorry. I still behave the same way.
In the meantime I have the version 27.1.0

@Michael2222 that PR is closed and superseeded by #40183
It will be shipped on 27.1.1. It doesn't mean it will fix this specific problem but feedback welcome nevertheless...

@solracsf yes, the problem is solved for new files. Thank you!
But for the old (currupted) files that I show as folder, I always show a folder.
I think I must re-read all files from my synology in the nextcloud meta-data datebase!?

Which command at command-line must I used, that I can start the re-read only the file from synology-NAS?

Try to rescan your files.
