Credentials given in this tutorial to register the host through subscription-manager register are not working. looking for help

[Travis]

@Grshkmr -

You might want to put a little more context here and possibly start a topic for your question. You mention a tutorial and credentials, but there is no point of reference.

If it is for the course there should be a guided exercise and name and section and possibly a step number. If it is for something else, then specify where it came from so you can get an answer.

subscription-manager is used to register systems either to Red Hat or a Red Hat Satellite. In the course, we are doing some installations and configurations to make systems register to a local satellite. If you are using subscription-manager outside of the course or without the configurations for a satellite, it is attempting to register directly to Red Hat, then definitely the credentials wouldn't work and you would need to use your own Red Hat account to register those systems.

If you see a "Fail" for "Verify CDN listing" portion of any "lab start" commands showing "Expected: 0 Received: 7" , ssh over to "utility" server as student. Sudo to root, systemctl status nginx, (suspect you'll see its in "failed" state), systemctl start nginx, systemctl status nginx. Hope you'll see it now in "active (running)" state )

Hello people
After a week trying to connect logged into to this lab using SSH private key , as i was being using for other  labs with success, this does not work for me.

$ ssh -F ~/.ssh/roleRH403.conf workstation
The authenticity of host '[159.135.175.140]:22022 ([159.135.175.140]:22022)' can't be established.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

any help will be appreciated. TIA

more info.
After deleting and recreating the lab (with different external public IP given to me),

no luck either, not possible to connect to workstation

mylaptop$ ssh -i ~/.ssh/rht_classroom2.rsa -J cloud-user@159.135.175.140:22022 student@172.25.252.1 -p 53009

I pulled down the key from training GUI.  Set perm to 0600.

jwesterd@jwesterd-thinkpadp1gen4i.rmtusnj.csb $ ls -l ~/.ssh/rht_classroom.rsa
-rw-------. 1 jwesterd jwesterd 2488 Sep 24 09:58 /home/jwesterd/.ssh/rht_classroom.rsa

Copied the string to the CLI (fedora 40), and ran it.  Connection timed out.

jwesterd@jwesterd-thinkpadp1gen4i.rmtusnj.csb $ ssh -i ~/.ssh/rht_classroom.rsa -J cloud-user@a.b.c.d:22022 student@172.25.252.1 -p 53009
ssh: connect to host 148.62.92.63 port 22022: Connection timed out
Connection closed by UNKNOWN port 65535

Compared IP address to the referenced one in the lab: "Public Ip: a.b.c.d". Yup. good.

Thanks   @westerj  firstly.

On my Fedora38, that same process amde in many other several trainings that worked for me, in this case it is not.

Point i have made/tried it with 3different external IPs (after deleting and recreating the lab).  So my guessing is , i dont know what is happening
