A special scenario: When you reuse an IP address from a Node or WebRTC Gateway, the SSH connection will fail because their fingerprint will have changed. As a result, you will be warned of a possible security failure (a connection against a known host is expected, but instead the found host is another). You can see an error in the trace logs of Presence OpenGate web services. To fix this problem, connect to this module and clear the entry which causes this conflict in the /var/lib/ua/known_hosts file. If the listed hosts are known to you and you are sure that this is not a security issue, you can execute the following command: docker exec -it webservices_og rm /var/lib/ua/known_hosts. This will clear all known hosts and the new hosts will automatically be accepted.
