Invalid Host Key, Unable to Reclaim the Host Role – Webex
Invalid host key; the host role cannot be reclaimed at this time.
Every time another player challenges the current one to take over as host, the host key is forced to evolve.
Solution:
The host key was removed from each and every email template beginning with version 40.0 of the Webex Business Suite (WBS).
In October of 2020, Cisco made an announcement on host key rotation. In order to avoid illegal usage of the host key, the host key for a meeting will now automatically renew after the meeting comes to a close.
