3CX SSL certificate has expired

Follow these steps to renew your 3CX SSL certificate (assuming that the PBX in question is SP0 as the last contact with 3CX servers has been made from a 15.5 SP0 – In this case the system must be updated to the latest service pack)

To force the update:

  • If version is lower than v15.5 SP2 skip this step:
    • Starting from v15.5 SP2, go in Settings / Parameters:
    • Set or Add TEMPORARY_SELF_SIGNED_CERTIFICATE_GENERATED and give it value of 1.
  • Linux:
    • Log in via SSH.
    • Type: /usr/lib/3cxpbx/PbxConfigTool -renew-certificates
  •  Windows:
    • Go to Command Prompt.
    • Type: “C:\Program Files\3CX Phone System\Bin\PBXWizard\PbxConfigTool.exe” -renew-certificates
    • Press Enter and the result should look something like this:
    • Restart nginx just to be sure and the certificate should have been renewed (service nginx restart)
I got the instruction above official from 3CX Support Helpdesk.
