Additional information:
 * Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS or FWaaS services. Geneve will be used as the encapsulation method for tenant networks
 * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
 * File /root/keystonerc_admin has been created on OpenStack client host 192.168.168.171. To use the command line tools you need to source the file.
 * To access the OpenStack Dashboard browse to http://192.168.168.171/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.

Error: Could not prefetch cinder_type provider 'openstack': Could not authenticate
Error: Failed to apply catalog: Could not authenticate

I could see that people have experienced the similar issues but those solutions did not work for me. I also have done below steps.

• Verify the hostname and host file
• Opened the port or disabled the firewalld
• Disabled the SELINUX

I changed hostname to openstack and here is my host file

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
<my-ip>     openstack

I am not sure is that a hostname issue or firewall or anything else. I have been struggling this for quite sometime and a help would be greately appreciated

Answer 1

I met the same question.Maybe you can modify your /etc/hosts and add your hostname in it not openstack.
