Issue with License

[gregory.b]

Dear all,


I have an issue with a 3CX license that doesn't seems too refresh.


We have already renewed the license before it's expiration but when we try to refresh we get this error message.



Can you please advise what could this issue come from

As thr 3CX was working find before

External access via FQDN is working fine.

Edited by a moderator: The screenshot has been removed due to exposing the license key.

Which build number / version is your pbx? Looks like your way behind with your updates.

version 20 build 5 only

We didn't upgrade yet but this could not be the reason why we get this error and our SC is 0

Exactly, you need to be running at least U6 but better go to the latest which is U7 once you get a chance.

There you got your problem. U5 cant connect anymore. You need to be at least on U6 as @ChrisC_3CX already said.
