No, you definitely do not need to configure a web server on the compute 
node.

My guess is that the [keystone_authtoken] section of your nova.conf file 
on either or both of the controller and compute nodes is not correct or 
doesn't match what you have in your rc file for the openstack client.

The nova-status command and the service daemons in Nova do not get their 
connection information from the rc file that the openstack client uses. 
Instead, they look in the [keystone_authtoken] section of the nova.conf 
files.

So, make sure that your [keystone_authtoken] section of nova.conf files 
contain proper information according to this documentation:

https://docs.openstack.org/ocata/config-reference/compute/nova-conf-samples.html
