I've found nothing obvious (404, 503, ...) anywhere

Chrome inspect element:

<image x="0" y="0" width="32" height="32" preserveAspectRatio="xMinYMin meet" filter="url(#invert)" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//apps/calendar/img/calendar.svg?v=39ca7278c6fa212603203868d85efa90" class="app-icon"></image>

This is what i get when copying the link address in firefox:

https://apps/calendar/img/calendar.svg?v=39ca7278c6fa212603203868d85efa90

Blowing up to valid full url, the icon gets displayed correctly.

@morph027

Can anyone of you reproduce this @nextcloud/designers? Any idea what the issue could be?

@morph027 does it happen ona different device too? And also in an incognito window?

Yes, different devices, different browsers (Firefox, Chromium, Midori) and all of them tried native and incognito.

Hm, now it's gone ;)

Probably some nginx or apache cache related staff.
