i use NC 18.04. After upgrade from NC 17 to NC18.1 my previews are not working.
If i click in the Share button, the Windows in the right corner are clear. With NC17 i have the previews of the PDF Files.
When i look with web tools, i see the following:
1. Request URL: https://xxxxxxxxxxxxx/core/preview?fileId=29383&x=1680&y=1050&a=true 2. Request Method: GET 3. Status Code: 404 4. Remote Address: xxx.xxx.xxx.xxx:443 5. Referrer Policy: no-referrer
I have already start the preview generatot with occ preview:pre-generate
But always the same.
Can anybody help?
