I have a client running 3CX v 15.5 Update 2 (yes I know it is out of date).
I am trying to update them to version 15.6 so I can update them to v16. but when I go to the update page and select the update, it says that the maintenance is expired and the updates are not available.
I purchased the Renewal through Telin and they confirmed that the maintenance is up to date. I spoke to their tech support and they recommended that I change the primary DNS to 8.8.8.8 (Did not work).
I did a firewall check and the PBX passes everything.
When I am on the activation page, and refresh the key, it says that the PBX could not establish a TCP connection to activation.3cx.com. (See screenshots)
