Make sure nextcloud is running on your pc and couldn't update placeholder info

Nextcloud version: 25.0.3 based on NextCloudPi Image v1.51.3
Operating system and version: Debian GNU/Linux 11
Apache version Apache/2.4.56
PHP version : 8.1.18

The issue you are facing:
On my Windows 10 laptop running nextcloud client 3.8.1 if I try to click on a file using the right menu option “Always keep on this device” or if I try to open a file I receive a pop up with this error for every file :
Make sure nextcloud is running on your pc

Clicking on the nextcloud icons I see a lot of errors:
couldn’t update placeholder info

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Right click on a file
  2. Always keep on this device

File is missing

An update on this issue, enabling the log file I found this
Dehydration of the cloud file is disallowed by the cloud sync provider
But I didn’t understand what type of error is

sounds like there is an issue with the cloud storage API… I saw similar issues this long time ago when VFS was new… didn’t saw this with newer versions. I think this can happen when NC desktop client crashes/is killed by the user… as far I remember reboot of the client helped… the problem must be more or less completely located on the client because de/hydration of placeholders has more or less nothing to do with the server (as long the server is available and file download is successful).

On the server following is strange:

as you can’t bind valid public cert to a local hostname either this is wrong or you are running self-signed cert which could result in issues as well. I would recommend you review Reverse proxy — Nextcloud latest Administration Manual latest documentation for required settings and values (add overwritehost at least)

Hi @wwe
thanks for your help, I uninstalled Nextcloud and removed all folders under AppData then I reinstalled it and now it works.
