Viewer does not show images on public shared links 18.0.4 #500

Describe the bug I recently updated my nextcloud instance from 16.x over 17.x to now 18.0.4. When I create a public link, the viewer opens but shows only an endless loading animation. Here is such a link: https://cloud.lightframefx.de/index.php/s/37qznEAKkJDGbkj

Since viewing functioned as expected some days before the update, I guess no server setting should be the problem. But since my Nextcloud instance lies on a shared hoster, I can't completely rule out that anything changed on the hosters side.

To Reproduce Steps to reproduce the behavior:

  1. Create a file folder
  2. Drop some images there
  3. Share the link publicly
  4. Click on any image

Expected behavior A lightbox should open so that anyone who gets the public link could watch and cycle through the images.

Screenshots When opening the link, console shows this: Screenshot_20200522_165250

There are some GET requests denied because of CSP, but they get loaded later (third screenshot), so I’d guess that that’s not the problem: Screenshot_20200522_165742-1 Screenshot_20200522_165908

After clicking one of the images, the network tab shows this error, and keeps showing the load animation forever: Screenshot_20200522_170358

You have to enable the sharing option: "Allow users on this server to send shares to other servers" Then it will work.

Well, yeah, that did the trick. Kind of illogical, because I didn't change any options, and it worked before the update, but I can follow the arguments on the thread you posted. So thank you very much!
