ERR_NGROK_702

Message

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. Please decrease your inbound connection volume or upgrade to a paid plan for additional capacity.

Further help

If you're having trouble resolving this error, please reach out to support@ngrok.com

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.
