We have run zammad run rails precompile:assets but it doesn’t fix the problem. :woozy_face:

Can someone help me how we can reconnect the colleagues

Technically this is the same issue like this one:

All currently functioning clients will stop working as soon as you clear the browser cache.
Only solution I know of currently is renaming the compiled files Zammad looks for. You can find them in /opt/zammad/public/

As I wrote in above mentioned thread, this is a rare issue I don’t really encountered often. I’ve seen this once on a instance I own, but can’t tell where this comes from. It never striked me again
