Unable to create, view, modify tickets withing Teams

since today we are unable to interact with tikit, helpbot via Teams.

Reply is Allways “I don’t know what just happened there” – or APP Cannot be contacted when we try to create Ticket using the contect menu.

Creating tickets on web.tikit.ai works flawlessly:

Create ticket on web.tikit.ai > Requester and triage Channel get Teams notification > User and Agent are unable to reply/edit in Teams – ERROR “I don’t know what just happened there, but I’ve gone ahead and alerted the right people. Just to make sure it wasn’t me, here are the things that I do know…”

Updates(ex reply, changes) made on web.tikit.ai do show up in Teams

Any ideas what to check?
Tikit 1.11.0
HelpBot 1.0.4
