<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Logs are too general.
<br>
<br>
let me give you a few leads.<br>
<br>
1. Check the mysql connection string inside /etc/neutron/neutron.conf and see if it is valid.<br>
2. Check the keystone_authtoken section inside the same file and verify if they are correct and if the specified user/tenant(neutron/service) is available in keystone.<br>
3. See if the neutron-server is running. If yes see if it is responsive . may be do a 'neutron agent-list'. of course after setting the auth credentials in environment variables.<br>
4. See if all the agents (openvswitch/l3/dhcp) are in good state.<br>
<br>
If you see any of your agents or if the neutron-server itself is down please share your config file and log while restarting.<br>
<br>
