knotd still fails to start if it can't load certificates or keys. This appears to be a bug given that "knotd: server crashes when it fails to load a QUIC/TLS key" is in the release notes for knot-dns v3.5.6. Below is a patch that allows the server to start if knotd can't load the certificates/keys. ---  src/knot/server/server.c | 7 ++++---  1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/src/knot/server/server.c b/src/knot/server/server.c index 8de6f1a8f..e03178144 100644 --- a/src/knot/server/server.c +++ b/src/knot/server/server.c @@ -824,9 +824,10 @@ static int configure_sockets(conf_t *conf, server_t *s)      s->quic_active = conf->cache.xdp_quic > 0 || convent_quic > 0 || quic_rmt_count(conf, C_QUIC) > 0;      s->tls_active = convent_tls > 0 || quic_rmt_count(conf, C_TLS) > 0;      if (s->quic_active || s->tls_active) { -        if (init_creds(conf, s) != KNOT_EOK) { -            server_deinit_iface_list(newlist, nifs); -            return KNOT_ERROR; +        int ret; +        if ((ret = init_creds(conf, s)) != KNOT_EOK) { +            log_error("failed to configure server credentials (%s)", +                      knot_strerror(ret));          }      }
