ZNC
└─ Connecting via Halloy

Here's an example of connecting to ZNC via Halloy:

[servers.libera]
nickname = "paveloom/libera"
server = "znc.paveloom.dev"
password_file = "/home/paveloom/.config/halloy/password"
dangerously_accept_invalid_certs = true
use_tls = true

Note that accepting invalid certificates is necessary if a signed SSL certificate wasn't set up for the ZNS endpoint.
