Hello,

I urgently need help recovering administrator access to my self-hosted 3CX PBX.

PBX details:
- Self-hosted / on-premise 3CX PBX
- Version: 20.0.995 SP9
- BASIC 4SC
- 4 simultaneous calls
- PBX FQDN: royalzeus.3cx.com.cy
- Management URL: https://royalzeus.3cx.com.cy:5001
- Company: RoyalZeus Global Advisors LTD

Problem:

My current public IP has been blacklisted by the PBX, and I can no longer access the PBX Web Client or Admin Console.

At the same time, I have forgotten the PBX administrator password.

I have tried the PBX password recovery procedure, but the recovery email is not arriving.

I DO have access to the 3CX Customer Portal, and I can see the license associated with this PBX. However, I understand that Customer Portal credentials and PBX administrator credentials are separate.

I need urgent assistance restoring administrator access to the PBX and removing the IP blacklist.

I can provide proof of ownership and license information privately if required.

Please advise the fastest supported recovery procedure for this situation.

Thank you.
