I have 2 Trio 8800 that was working fine, now they are getting the message Failed to Fetch Root Certificate. Below is an example of what the error log is showing. I have not imported any certs, and skype for business is controlled by the home office in Switzerland.
The Trio 8800 is running Current software version: 188.8.131.5282

Hello @SuGA ,
Welcome to the Poly Community.
This could have multiple root causes.
You can try and amend the logging:
Change the above and then reboot the unit and share the logs (rename into .txt) via Diagnostics > View & Download Logs > UCS Application > Export
If you are unable to do so and no other community volunteer can help the next step is to raise a ticket.
In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.
End Customers are usually unable to open a ticket directly with Poly support. Available End User Poly services offerings are detailed here
If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.
If the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
