3CX Licence Registration Failure

[mshakarho@interranetworks]

Currently migrating a customer's 3CX instance to a new server. Following the installation and restoration of the backup, we encountered an issue with licence key validation, preventing us from completing the migration.

If the license is in fact valid check that you aren’t blocking outbound connections and aren’t re-writing https packets.

Ensure that 3CX Services are allowed as per guideline here.
