Unable to reach admin portal V16 Windows

[bpsinc]

I have a legacy client that is running version 16. I tried to contact them several times to upgrade to the latest version before their ssl expired.

I didn't push the issue aggressively, thinking I could still locally work on the phone system when they ultimately call for service. Fast forward to now, since the ssl expired I can't get into the portal.

Ideally, at this point I would like just like to grab a current back up and then move them to the Debian install.

Anything I can do to get into the management portal or kick off a back up? I know its running the windows embedded nginix install from years ago. I am running into road blocks, hopefully there is a work around.

TIA

Which browser are you using? Normally one can just tell the browser to proceed anyway and accept/ignore the expired cert. In Chrome and Firefox click the Advanced button/link on the error page.

try connecting to the 3cx server on the http port I.e http;//192.168.0.2

I searched and searched for the command line backup. My googlefoo failed me. Just started a backup, I will see what comes of it when finishes.

I have tried multiple browsers, both local (on the server and LAN) and through FQDN. Just keep getting a site can't be reached.

This is not due to the expired certificates. It legitimately cannot be reached.

Your best chance is to sign in to the Windows server, and try accessing the management console from there.

http://{machine_ip}:5000 would be the default way of reaching the management console on the machine itself.

Regardless, if you manage to get a backup via command line you can simply upgrade them to V18 by restoring that backup on a fresh install. Make sure you read the requirements because old versions of Windows Server are no longer supported.

Or... use our ISO and go with Debian. You don't have to worry about the OS or licensing Windows
