What's up with this error and clients reconnecting rapidly?

Seems to be this code...

    monitorIncomingConnections() {
        const firewall = this;
        const { ssb, config } = firewall;
        ssb.auth.hook(async function (fn, args) {
            var _a; 
            const source = ssb.id;
            const [dest, cb] = args;
            if (config.rejectBlocked) {
                const [, blocked] = await run(ssb.friends.isBlocking)({ source, dest }); 
                if (blocked) {
                    debug('prevented blocked peer %s from connecting to us', dest);
                    cb(new Error('client is blocked'));
                    return;
                }   
            }
            if (config.rejectUnknown) {
                if (firewall.outgoingAttemptsMap.has(dest)) {
                    fn.apply(this, args);
                    return;
                }   
                const [, hops] = await run(ssb.friends.hops)({});

                    cb(new Error('client is a stranger'));
                    const ts = Date.now();
                    const previousTS = (_a = firewall.incomingAttemptsMap.get(dest)) !== null && _a !== void 0 ? _a : 0;
                    firewall.incomingAttemptsMap.set(dest, ts);
                    if (previousTS + INCOMING_ATTEMPT_RECENTLY < ts) {
                        firewall.notifyIncomingAttempts({ id: dest, ts }); 
                    }   
                    firewall.saveOldIncomingAttempts();
                    return;
                }   
            }   
            fn.apply(this, args);
        });
