Hi guys,
i have run under Docker a instance of Vaultwarden.
Since today i become in Log a entry:
[2026-01-28 14:48:28.351][vaultwarden::api::icons][WARN] Blocked address: 192.168.178.5
[2026-01-28 16:50:12.976][vaultwarden::api::icons][WARN] Blocked address: 192.168.178.5
Does it have anything to do with the fact that I installed fail2ban?
Can everybody tell me why i have this failure?
No. Vaultwarden would not be aware of IP addresses blocked by fail2ban.
Because by default Vaultwarden will block requests to reserved/private IP address ranges
/// Block non global IPs |> Enabling this will cause the internal HTTP client to refuse to connect to any non global IP address.
/// Useful to secure your internal environment: See https://en.wikipedia.org/wiki/Reserved_IP_addresses for a list of IPs which it will block
http_request_block_non_global_ips: bool, true, auto, |c| c.icon_blacklist_non_global_ips;
