root@server
cscli decisions delete --ip 198.51.100.10

Removes all active decisions for the given IP, and the bouncer lifts the ban shortly afterwards. If the same scenario triggers again, the IP is banned again. For permanent exceptions, use an allowlist or a whitelist parser.

Note: Check the current list first with cscli decisions list --ip <adresse>.
