Hi Team, We were trying to provision Overcloud Nodes using the Tripleo wallaby release. For this, on Undercloud machine (Centos 8.4), we downloaded the ironic-python and overcloud images from the following link: https://images.rdoproject.org/centos8/wallaby/rdo_trunk/current-tripleo/ After untarring, we executed the command *openstack overcloud image upload* This command setted the images at path /var/lib/ironic/images folder successfully. Then we uploaded our instackenv.json file and executed the command *openstack overcloud node introspect --all-manageable* On the overcloud node, we are getting the Timeout error while getting the agent.kernel and agent.ramdisk image. *http://10.0.1.10/8088/agent.kernel......Connection <http://10.0.1.10/8088/agent.kernel......Connection> timed out (http://ipxe.org/4c0a6092 <http://ipxe.org/4c0a6092>)* *http://10.0.1.10/8088/agent.kernel......Connection <http://10.0.1.10/8088/agent.kernel......Connection> timed out (http://ipxe.org/4c0a6092 <http://ipxe.org/4c0a6092>)* However, from another test machine, when I tried *wget http://10.0.1.10/8088/agent.kernel <http://10.0.1.10/8088/agent.kernel>* - It successfully worked Screenshot is attached for the reference Can someone please help in resolving this issue.
