Cannot open file png on public link

[ScharfViktor]

Describe the bug

Steps to reproduce the behavior:

1. add a png file and open it in mediaviewer (opened correctly)
2. create public link and open public link
3. open png file in mediaviewer

Expected behavior

The pnd file can be opened in mediaviewer

Actual behavior

Error 500
2021-12-10T14:07:21+01:00 ERR could not get thumbnail error="{\"id\":\"com.owncloud.api.thumbnails\",\"code\":500,\"detail\":\"could not get image from source: could not get the image \\\"https://127.0.0.1:9200/remote.php/dav/public-files/VBWKXTWsWiWyuNo/amoadklbbpmdaabc.png/amoadklbbpmdaabc.png\\\". Request returned with statuscode 403 \",\"status\":\"Internal Server Error\"}" service=webdav

BUT: If you create a public link to a folder with a file, it works correctly

Setup

Please describe how you started the server and provide a list of relevant environment variables.

OCIS_VERSION=v1.16.0
BRANCH=v1.16.0-rc2

[C0rby]

I tested it with the 1.16 release and it works. Could you try again?

I might have more information on this. I noticed the same - at first it seemed random, but by now I think it might be dependent on the resolution:

Warning: Binary output can mess up your terminal. Use "--output -" to tell 
Warning: curl to output it to your terminal anyway, or consider "--output 
Warning: <FILE>" to save to a file.

Right now I can reproduce 100% of the times. The only difference in those requests is x=1280&y=1280 vs x=3840&y=3840.

edit:
Hmm.. In my output I see error 401 and in the original report it mentions something with 403. So not sure this is the same issue, but who knows - maybe it still helps

Fixed in 2.0.0-beta1
