Steven and I managed to get it working again
The problem was the introduction of a load balancer, so we only saw the balancers IP.
Steven implemented a data endpoint with the fixed IPs of the boxes, and I changed the wechall part a bit.
New: There are now 2IPs per warbox, which i implemented via a new field "wb_ip2" (dont try this bad practice at home)
Happy Challenging and thx Steven!
