Slideshow Instagram integration not stable

Somtimes the integration of Instagram-Posts works fine - sometimes I get the following message:
SLIDESHOW CK ERROR : NO IMAGES FOUND ON INSTAGRAM
See on site: www.theangrymoose.de/
Yesterday I saw the posts, today the error occurs without editing something ... don´t know why

Hi
Please tell me how you have configured the module in the instagram source so that I can try by my side
CEd

just tested by my side, it works
please clear the joomla cache and tell me if it works again

No it doesn´t work, even after clearing the cache

Same problem on an other site:


On all my sites "admintools" is installed - could that be the problem?
