I have a three node installation of openstack, everything works fine before. But now i can't ping or ssh the instances in openstack.
I can ping the ip of the controler and the networker, also from my controller i can see that all nova agents are up and the same thing for neutron-agents
I can ping the gateway to the external net from router namspace. I can also ping the subnet interface from router but i can't ping the instance using the floating ip adress
Can someone help me fix this issue?
Thank you
Please restart Neutron services on controller, networking and Compute nodes.
