MSTP Setup not working

Hi,

I have 3 Netonix switches in a loop with 1 Mikrotik Cloud Core Switch, all running MSTP (and routers attached OSPF). The VLANs are set correctly on the ports, and the MST Instance for each VLAN is correct and shows forwarding on the correct ports. Got everything working perfectly, then after about 5 hours with no changes the one Netonix started discarding all traffic on the one port. The VLAN Instance shows forwarding, but CIST shows discarding - Alternate. I do not understand why it just started discarding the traffic. I have tried everything I can think of? Can someone help? What screenshots will you need?

Is firmware 1.5.5 ? Something writen on log ?

Ports, vlan and STP config with a network schema would be the first thing to provide.
