# Error 702

## ERR\_NGROK\_702

Too many connections! The tunnel session `SESSION` has violated the rate-limit policy of `THRESHOLD` connections per minute by initiating `COUNT` connections in the last `SECONDS` seconds. Decrease your inbound connection volume or upgrade to a paid plan for additional capacity.

### Additional Info

* ngrok limits the number of inbound connections to your tunnels.
* Limits are imposed on connections, not requests. If your HTTP clients use persistent connections aka HTTP keep-alive (most modern ones do), you'll likely never hit this limit.
* ngrok will return a `429` response to HTTP connections that exceed the rate limit.
* Connections to TCP and TLS tunnels violating the rate limit will be closed without a response.

### Possible Solutions

* Upgrade your account to a Pro or Pay-as-you-go plan from your [account dashboard](https://dashboard.ngrok.com/billing/plan) in order to reserve a custom hostname.
