Universal viewer - "download current view" not working

When I try to download current view, I get:

Page not found.

error-controller-cannot-dispatch

If I try to download PDF, everything is ok, but when trying to download current image I get that error. Also, is there a way to configure UV so a user can download current image or complete item consisting of several images).

Tnx

It seems that UV is looking for images at the wrong path, but I can not find any configuration settings in UV, IIIFImageServer or in ImageServer module to configure that.

Also I have another problem with UV, almost regularry, first image is not shown, it just spinning loading indicator but nothing is happening. If I click on any other image in that item, it shows instantly, but first image is usually not shown. I tried on 2 installations, I have on ona linux machine testing and on other production installation, but it is happening on both installations.

My module versions are:

IIIF Server 3.6.24
Image Server 3.6.19
Universal Viewer 3.6.9

Unfotunately, I can not give you direct link because all my installation are behing firewall and for internal use in our institution.

Strange - if I click on “full screen” it shows that image. I tought that it is browser related but it happens in Chrome and in Firefox the same.
