I am installing openstack using ( (rocky)

I am stuck at neutron installation. I am using the (Networking Option 1: Provider networks). After all the steps and at the verification when I run : $ openstack extension list --network

I get the below error:

REQ: curl -g -i -X GET http://controllerstack:9696/v2.0/extensions -H "Accept: application/json" -H "User-Agent: openstacksdk/0.17.2 keystoneauth1/3.10.0 python-requests/2.18.4 CPython/2.7.15rc1" -H "X-Auth-Token: {SHA1}2e862b28c61bdb114ca81e4ace5c9723d4c25270"

Retrying in 0.5s.</urllib3.connection.httpconnection>

I don't know what is the issue. The name of my controller is controllerstack and I have the right ip address mentioned in /etc/hosts and furthermore, I have no spelling issues in nova.conf.

I was able to fix the issue. I had to restart the memcache service. I still keep getting the errors every now and then. And when I do :

  1. service memcached restart.
  2. Clear browser cookies and cache.

But it is sometimes still annoying even with the fix.

Connection refused means that you reached controllerstackand its port 9696 is not blocked, but nothing listens at that port. The Neutron server is down or uses a different endpoint than http://controllerstack:9696.

Check if it runs. If not, check the /var/log/neutron/server.log (I hope the filename is correct) to find out why it doesn’t run. If it does run, again check the log to understand why it is not listening on that port.
