Issue: 502 Bad Gateway Error with LocalTunnel on React.js Project

Description: I'm encountering a 502 Bad Gateway error when using LocalTunnel with my React.jsproject. The error occurs intermittently and affects my ability to test my application locally. Below are the details of my setup and the steps I've taken to troubleshoot this issue.

Project Setup:

React Version: 19

Node.jsVersion: 22.3.0

LocalTunnel Version: 2.0.0

Operating System: Windows 11

Steps to Reproduce:

Start the development server using npm start.

Open a tunnel using LocalTunnel with the command lt --port 3000.

Access the provided URL in a browser.

Observe the 502 Bad Gateway error intermittently.

Troubleshooting Steps Taken:

Verified that the LocalTunnel service is up and running.

Updated all dependencies to their latest versions.

Restarted the development server and LocalTunnel service multiple times.

Checked for any known issues on LocalTunnel's GitHub repository.

Expected Behavior: The application should be accessible through the LocalTunnel URL without encountering the 502 Bad Gateway error.

Actual Behavior: The 502 Bad Gateway error occurs intermittently, preventing access to the application.

Request for Help: I would appreciate any guidance or suggestions on how to resolve this issue. If there are any additional logs or configurations needed, please let me know.

Hey all, the 502's are used by a bunch of people spamming the server with random requests. It's causing some ngnix issues, docker routing errors, and constant near-100% cpu usage 😞

I'll be adding some rate-limiting to ngnix + doing a few more optimizations that should hopefully help.

I'll post an update when I have one but in the meantime, the 502s dont last very long and usually go away by the time you refresh.
