v20 cannot send emails after upgrade from v18 = 5.7.0 Denied

[BthPOA]

Hi,

I realize, looking at https://portal.3cx.com/ that our licence after upgrade from 18 to 20, lost the FQDN and maybe it's the main reason to not be able to send emails.

How can we contact 3CX team in order to fix it?

Hi, yes, you need to reinstall the system and set a new fqdn, without that you can't use external services such as the 3cx smtp.

Hi,

server reinstalled and I used the option to 'restore' form a backup, but shows this message: FQDN already in use. Please choose another one.

Since I´m login to my account at 'https://portal.3cx.com/customer/systems', there is no FQDN in use for the subcription. Why this message appears??

I found an old thread about 'FQDN release' but right now in the portal, there is no option for that on menu.

Thread 'FQDN binding problem'

Jan 24, 2022

Hello Dear Support,
I have a problem with FQDN.
Unable to bind FQDN to license. When I try to bind the FQDN, I get the error "This FQDN is already in use. Please select a different name." This name was taken by our license, but it was changed to another one, now we need to return it back. Can you help with this?

I don't know if that issue is related with old subscription (2024 ~ 2025) which is still listed on the portal but there is no option to 'release FQDN'

 

[BthPOA]

The current subscription: the same issue with no option to release the FDQN

Hi 3Cx team,

as a customer, I would like to suggest to create a new collumn to display the FQDN directly without need click on the system to obtain that information.

Hello,

As I see you are using a custom FQDN? Could you please try to setup as new with your FQDN, not restore from backup in the portal, and then after it is setup do a restore.

The backup you are restoring from is V20, yes?

Hi,

For this specifically, if the FQDN is setup it does show

Hi @KyriacosS_3CX,

that is the problem, our custom FQDN are not shown in the portal ('my system') but when we try to restore shows a msg related with 'FQDN is already in use'.

Answering your question, 'yes' the environment is v20 with a custom FQDN.

Questions
#########
1) Can you (or 3CX team) do a internal research and release the FQDN at your side since we cannot do via portal (my system)?
2) Could we remove the old version (expired one) listed in the portal?? I think that it is the main issue.
