Replace License Key Error

[JohnH]

Hello, we just made Bronze partner and I was looking to upgrade our current internal tenant from a paid license to our new NFR. When I try to change out the key I'm getting an error

"A networking problem has occurred while activating your license key. (Error code: 401)."

The PBX has normal internet access and DNS is working fine, so I'm unsure what the procedure is from here.

I found a thread of someone having this issue because it was a V16 key and they were on V16, but for us it's a V16 key and we're on V18. Is there a way to update the key to V18 if that's necessary?

Hi @JohnH,

Congratulations on making Bronze Partner!

Can you send me the license key in question via PM (not here).

@JohnH what you are trying to do is not possible. You can not setup the NFR as a replacement key of a paid one.
NFR keys can only be the source.
If you want the fqdn of paid key then you have to go with the procedure, backup with no fqdn, uninstall machine, release fqdn from key and then set this up with your NFR.
