Unable to register/obtain subscription on RHEL 8 system

Latest response

Hi,

With a perfectly valid account (that I have used to login successfully to the Red Hat Customer Portal), I am (suddenly) unable to register a system from the CLI:

[root@kubmaster ~]# subscription-manager register --username MYUSERNAME --password MYPASSWD

Registering to: subscription.rhsm.redhat.com:443/subscription
HTTP error (401 - Unauthorized): Service not available, please try again later

Just for facts, I have a working NIC:

[root@kubmaster ~]# host subscription.rhsm.redhat.com
subscription.rhsm.redhat.com has address 209.132.183.108
[root@kubmaster ~]# ping subscription.rhsm.redhat.com
PING subscription.rhsm.redhat.com (209.132.183.108) 56(84) bytes of data.

rtt min/avg/max/mdev = 164.471/164.828/165.377/0.612 ms

So, I am not able to see something wrong.

[root@kubmaster ~]# nc -zv subscription.rhsm.redhat.com 443
Ncat: Version 7.70 ( https://nmap.org/ncat )
Ncat: Connected to 209.132.183.108:443.
Ncat: 0 bytes sent, 0 bytes received in 0.17 seconds.

Has something changed or something that I am missing?

Best regards,
