Manager unable to connect with Engine/Sandbox

Check for the log lines like below in /var/lib/triage/logs/<YYYYMMDD>.log on manager:

{“l”:”debug”,”pkg”:”backends.sandbox”,”backend”:”sandbox1” ,”error”:”HTTP 403 (FORBIDDEN) : Access to this resource is not allowed by this IP address” ,”ts”:*** ,”msg”:”Control connection error”}

During engine registration/installation, the engine IP needs to be an unused IP address in the 10.0.0.0/24 subnet (except 10.0.0.10, which is assigned to the manager).

The above logs would be observed if the IP is set outside of this subnet.

To address this issue, the engine must be removed from the manager configuration and re-installed to assign a new IP within the 10.0.0.0/24 subnet.
