How to access Polycom VVX GUI via IP after Povisioning? Need Admin Password to make changes.

We used to be able to access the GUI for changes by going to:

EX: https://192.168.1.67/

This password was:
- 456
- 72227
- MAC Address?
- Secret URL ###: "admn803864912024pwd" from ---> https://voicemanager.businessconnect.telus.com/application/company/phones/803864912024/details

But not we cannot get in, has there been an update that has changed how to access it?

I know I can still perform a hard reset by following this KB: https://support.ringcentral.com/article/Third-Party-Polycom-Phone-Not-Accepting-Default-Password.html

But this is not the solution because once the phone is provisioned we cannot make changes.

Please advise as we have a client who is wishing to change some soft keys and we need to access this.

Thank you in advance,

JB
