RCO Authentication expired
Severity: Medium
Applies to: RCO lock connections
The authentication token used to connect to the RCO server has expired. Users may experience issues opening doors until the token is refreshed.
How does RCO authentication work?
Unloc uses an authentication token to communicate with the RCO server. This token needs to be periodically refreshed by an administrator logging into the RCO software.
Why does this happen?
- Password changed — The RCO user credentials may have been changed.
How to fix it
Contact your RCO installer to hear if something has changed, and forward the information to Unloc Support.
Auto-Resolution
This insight resolves automatically when Unloc successfully authenticates with the RCO server again.
End User Notification
When this issue is detected, end users with keys to the affected lock(s) will see a warning in the Unloc app underneath the open button, plus a more detailed description when opening the door page.
