What is a 502 Bad Gateway Error?
Cloudflare is a service that caches copies of your website and serves them to visitors, which can improve performance and security. If Cloudflare is unable to communicate with your origin server, it will return a 502 Bad Gateway error to the visitor. This can happen for a number of reasons:
- There's a problem with your Cloudflare configuration.
- Your origin server is overloaded or down.
- Apps or themes are causing internal disruptions.
- There's a problem with your network.
Step-by-Step Guide to Fixing 502 Bad Gateway
Step 1. Check your Cloudflare DNS records
Start by checking that your Cloudflare is properly set up
- Log in to your Cloudflare account.
- In the left-hand dashboard, click DNS > Records.
- Verify that all your DNS records are correctly pointing to the designated IP addresses, especially the ones associated with your Shopify store in the DNS management section.
Step 2. Optimize your Shopify server settings
Server configurations can greatly influence your store's performance.
- Go to your Shopify admin panel.
- Click Settings > Domains.
- Make sure that your settings match Shopify's recommended settings, and that your primary domain is connected properly. This will help to ensure that your store remains accessible even during peak traffic.
Step 3. Identify and disable problematic apps or themes
Sometimes, internal conflicts are the unseen icebergs:
- Go to Apps and sales channels in your Shopify admin panel.
- Uninstall each app one by one, checking your store's functionality after each uninstallation. This will help you to identify the app that's causing the error.
- If you're using a custom theme, switch to a basic Shopify theme. If the error disappears, then the problem is with your custom theme. Always back up your current theme before making changes.
Step 4. Resolve network-related issues
A problem with your network connection or your device can also cause a 502 error. Try these solutions to resolve network issues:
- Clear your browser cache and cookies.
- Restart your browser or device.
- Try using a different browser or device.
- Try using a different network connection or VPN.
- Check if your firewall or antivirus software is blocking Shopify.
If you can't resolve an error on your own, consider contacting Shopify Support for assistance. Their team can investigate the issue and provide further guidance.
