Can't ping or ssh my VM in openstack

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

Can you ping external network gateway from router name space? Can you ping internal ip of the instance from router name space? - Farhad Farahi
Yes i can ping the public ip of my external gateway, and the internal ip from the namespace of the router - kikas
Please check the security group applied to the instance, is ssh access enabled ? what about ICMP rules? And check if you can ping outside from the instance (Checking if the snat working correctly) - Farhad Farahi
The IcMP and the SSH protocol are allowed, it's weird coz i can access and ping some of my instances and not others - kikas
Is this a production environment? if not I would restart nova-* and neutron-* services on controller, networking and compute nodes and try creating an instance. - Farhad Farahi

Thank you Farhad it solved my problem.

I followed this tutorial to restart the services. Must restart nova and neutron services on both controller and compute nodes.
