Closing this out. I believe the issue was not using Node v18. I have it working now.
Thank you, everyone, for the help!

No, it added it automagically.

@olivierlambert
It looks like it installed. So that's good news. But I can't keep it because it isn't free, right?

Ubuntu 24.04 Server. I can try XOA.

@ajpri1998 ..
However the commit that shows on the link you posted is different.
Yes, I checked my date and time. Also, I used openssl to verify too.

@olivierlambert
I'm using XO from source. Just downloaded it today. I actually used ronivay/XenOrchestraInstallerUpdater script.
Installed XCP-ng 8.2.1 last night.

When I go to add my host, it seems to do ok, but after a few seconds, the red triangle pops up with the message CERT_HAS_EXPIRED (see screenshot) . I'm using a CA authority certificate, not self-signed, which I double checked by using openssh that the cert is indeed still good.

Any thoughts as to what I might try?

Cheers!
