Openkm preview not working

[nishant8900]

Hi,
I am using OpenKM 6.3 CE in a Linux based system with LdapPrincipalAdapter.
while checking the preview for some files, I am getting the below mentioned error
All the files and folders are there in datastore but none of them can be previewed.

PDF.js v2.9.359 (build: e667c8cbc)
Message: Unexpected server response (500) while retrieving PDF "http://[url]:[port]/OpenKM/frontend/Converter?toPdf=true&inline=true&uuid=0f5217a3-360b-45ac-a8f5-8f9aa3aaaaa".

Code: Select all

It seems to be showing that file not found, but the files are visible in the UI and in Properties also it is showing the details.
Due to this, I am not able to download the file as well,
It appears to me like file are only showing on UI but are not found in OpenKM/datastore
Actually few days back, Our OpenKM Application stopped working due to which we had to restore it. But nothing was disturbed in the files and folder datastore, the files and folders in the datastore were left untouched.
it was working fine for couple of days but few days after that this issue is occuring.

Please let us know the issue for this error and how can we solve this.

This is a very strange file system location for the datastore:
\172.16.255.158OpenKMdatastore/2d/27/2b/b6/2d272bb6-be1f-4bbb-98b2-b2a1047d8daa

I suspect you have something wrong in the datastore location configuration, check the OpenKM.cfg configuration and ensure if you have modified the default OpenKM datastore location the path is right

If the path is right, ensure the user who's executing OpenKM have enough grants to access to the file from the terminal
