request license from temporary to long-term

Hello everybody,

I am facing some troubles in requesting long-term license (Appian 18, VM with Linux)

I have already get a temporary license (one week ago) and to get a long-term license I had fullfilled (at the license site)
the text box with the output of ./q that I had saved (one week ago)

But when I submitted, a mandatory (and unexpected!) box "FQDN host" appeared.

Then I ran again command: QHOME=.. ./q

This time, when I submitted, I have got following error messages:

There is already a pending request for this FQDN. Please request a license for a different FQDN or cancel this request.
Your Q output is invalid
The operating system in your Q output is not a recognized operating system or your Q output is invalid

Could you please give to me some suggestions or hints ? Am I missing something ?

Thanks in advance for your help, best regards.

Paolo
