Understanding ERR_TOO_MANY_REDIRECTS on Google Cloud Platform Load Balancer

If you’re encountering the error message ERR_TOO_MANY_REDIRECTS while trying to set up a load balancer on the Google Cloud Platform (GCP) for your WordPress site, you are not alone. This error can be quite perplexing and frustrating, especially after having a smooth experience without the load balancer. Let's dive into the issue and explore how to resolve it.

The Problem

In our situation, the user has a WordPress site configured in a virtual machine (VM) on GCP. While everything was working perfectly without the load balancer, the introduction of the load balancer triggered the ERR_TOO_MANY_REDIRECTS error, preventing the site from functioning. Here's a summary of the setup:

Website hosted on GCP using a VM

Load balancer configured with HTTPS frontend and HTTP backend

No explicit redirection set up in Apache or in the .htaccess file

With this configuration, the website experiences continuous redirection loops, which is the root cause of the error.

The Solution

The resolution to this issue involves ensuring that both the backend and frontend of your load balancer are using HTTPS. Here's a step-by-step breakdown of how to implement this solution effectively:

1. Configure Load Balancer Frontend and Backend to Use HTTPS

Change the load balancer settings to ensure both frontend and backend are set for HTTPS. This ensures that secure connections are maintained throughout the entire request-response cycle.

By implementing HTTPS on both fronts, you reduce the chances of encountering redirect loops.

2. Update Port Mapping for VM Instance Group

Initially, the troubleshooting user had both HTTP and HTTPS port mappings set up for their VM instance group. However, this setup can lead to confusion in handling requests, often resulting in redirect errors.

Change the port mapping to have only the HTTPS entry. This adjustment ensures that all incoming traffic is directed through a single secure connection, helping to prevent any potential redirection issues.

3. Test the Configuration

Once the changes are made, run tests to verify that both HTTP and HTTPS are now functioning without redirection errors. You should be able to access the site securely and seamlessly.

Conclusion

Dealing with the ERR_TOO_MANY_REDIRECTS error can be a challenging experience, especially when using a load balancer in the Google Cloud Platform environment. However, by ensuring that your backend and frontend settings use HTTPS, and simplifying your port mapping, you can eliminate unnecessary redirect issues and restore your website’s functionality. Always remember to run tests post-configuration to confirm everything is working smoothly!

By following these steps, you'll not only resolve the current error but also enhance the security of your website, making for a better experience for your users. Happy hosting!
