Unable to subscribe/register server

Posted on

Hi Community,
I am using the RHEL9 Developer version. I tried to patch the server by typing dnf update from the command line but got an error "no route to host." I ran the below commands, and it unregistered and removed subscriptions; however, now I am trying to register it and am getting a Network error. I rebooted the server, removed the machine ID, and recreated it. I removed the system from the Redhat portal as well, but I can't register the machine. I stopped firewalld and changed dns to 8.8.8.8 but still didn't work. I can see http and https services are added in the firewalld. I can ping I googled but couldn't find a solution. I can ping Google but get an unreachable error when I ping subscription.rhsm.redhat.com. Can someone help me fix the issue? Thanks

subscription-manager remove --all
subscription-manager unregister
subscription-manager clean
subscription-manager register
