I have a multi-layered problem.
The first part of the problem is that I have several Polycom Trio 8800 devices that are provisioned to trio.zoom.us to use as a Zoom Rooms controller. The devices are now unable to log into Zoom Rooms, and when I direct the user to do so with a valid Zoom Rooms login and/or activation code, it says: "Security Warning: Untrusted Server Certificate | You are unable to connect to Zoom because the security certificate presented could not be verified. Contact your IT department for assistance." There are no settings options when this appears.
I tried to https into these devices through their IPs to see if I can update the Zoom cert. However, each device was left at the default 456 password before I sent them to the offices (I know, my bad). So the second part of the problem is that when I try to https into them, it brings me to a blank page that says "Default admin password is in use. Change the password.", and it has no option to change the password or get into the admin page like normal.
Could these two issues be related? I could have my users try to manually change the password at the device, but they're locked into the trio.zoom.us provisioning, so I'm not sure it could be done at the device level using Menu Key => select Settings => select Advanced => current Password => select Admin Settings => scroll to Change Admin Password. Is there any way to either bypass the Zoom provisioning and let the user change the password in the device settings, or preferably, remotely change the password of the devices when it's throwing the "Default admin password is in use" error?
I also found this article with a similar issue, but it's for devices provisioned to MS Lync, so I don't think they're related, plus I didn't see an actual solution there: https://community.polycom.com/t5/VoIP-SIP-Phones/quot-Default-Admin-is-in-use-please-contact-your-administrator/td-p/60636
