Shopify 502 Bad Gateway Error
Yes, the query results are stored in cache. Even if you get a 502 error, most of the data is already cached. This means that you will be able to retrieve all the data without having to wait for it. It is possible that your query for data may time out depending on the current platform load and server load. The re-try that you are doing is a good idea. Other good practices for avoiding API timeouts include requesting for less data at one time, and using pagination in your API request (https://help.shopify.com/en/api/guides/paginated-rest-results)
I keep (randomly) receiving a 502-BadGateway error from the Shopify Order API.
From what I can see this is only occurring for one specific shop we are working with (although the Shopify Status Page does not mention any problems).
Is there a Shopify Developer here who can have a look at this?
The error happens quite frequently (every 3 or 4 requests) and blocks us from preparing an important accounting export.
What is 502 Bad Gateway Error and How to fix it (Easy Guide to Fix)
Consumers and web owners both are frustrated when an error code appears on a website or one of its pages. The 502 error, or bad gateway error, is one of those annoying bugs.
This error is not as common as others, but it can be very frustrating when it occurs. It’s also often hard to pinpoint the cause.
What is the 502 bad gateway error?
This error is HTTP status code (Hypertext Transfer Protocol). It occurs when an online server fails to receive or believes it did not get a response from another server.
This error can occur on any system, browser, or device. Let’s find out what is causing this error, how to fix it, and hopefully, get rid of it forever.
The 5xx Gang
You may be aware that the 502 error isn’t the only one that could occur from the 500 series. There are many other errors that could also happen that could ruin your day. Here are some of the most important and common errors in the 500 group you should be aware.
- 500 Internal Server Error- This error is displayed by your web server when it encounters an issue that hinders it from performing its task. Client request.
- 501 Not Implemented: The server can’t support or recognize the requested method. It does not have the necessary functionality to process the request, so it returns this error.
- 502 Bad Gateway – Servers got into a fight and aren’t talking to one another anymore. Jokes aside: Your server failed to receive a response from the upstream server when it attempted to process the request while acting as a proxy.
- 503 Service Unavailable: A temporary situation in which a server is unable to process requests due to maintenance or overloaded.
- 504 Gateway Timeout: The server that was acting as a proxy/gateway again, didn’t receive a timely response from any other server, such DNS, and it couldn’t process this request.
- 505 HTTP Version Unsupported – This error means that your web server is unable or unwilling to support the HTTP protocol version requested. The error typically includes a description of the reason why the server won’t cooperate.
502 Error: What causes it?
The 502 error in most cases is a communication problem between two servers online. It is not something that could be considered serious or major. It can sometimes be difficult to determine the exact cause of a 502 error.
This error is caused by two online servers that you have no control over.
Web owners who aren’t developers can benefit from having one in their team to help with errors. To get an idea of what to expect from a developer, you can search online to find software engineer jobs.
This error can also disguise itself as HTTP 502, 502 Proxy Error or 502 Bad Gateway NGINX. Here are some common causes of the error.
- Your server’s origin server is down – This means that your server may not be functioning properly. Your problem could be caused by a connectivity issue or server overload, excessive traffic, etc.
- Domain name problems – When the domain is having trouble determining the IP address correctly, this problem can occur. This issue could be caused by incorrect DNS records at the Domain hosting level. The error could also be due to insufficient time for DNS changes to propagate globally. This could be due to slow TTL (Time To Live).
- Firewall blocks requests – Ah, yes, that firewall with all its security problems. If you are unsure about the problem, make sure to check the firewall. The firewall is usually responsible for the 502 error. It can prevent requests from being served, particularly on WordPress websites with security plugs. It can also trigger DDoS protection.
- Server failure – Your server died. This could happen for many reasons. This could be due to maintenance, a server crash, or because the content on the server is not in compliance with the terms and conditions of the provider.
- Browser error – Sometimes browser extensions are the cause of our 502 errors. This is especially true if you have AdBlock extensions which protect users against annoying pop-ups and ads. A browser version that is out of date could also be a reason.
How to fix the 502 error?
We’re now getting to the fun part. It is often very simple to fix a 502 error. This can be done from a user’s perspective by simply reloading your page. There are many ways to correct this error. Here are some of them.
- Reload the page – This will remove the error from the page. The poor thing might just need a little more time, as we have already mentioned.
- You can also open a new browser session by closing all tabs, clearing browsing history, cookies, cache and reopening the session. You may also be able to fix the problem by creating a new incognito or private session.
- Restart your computer. If all else fails, you can reset it and start over.
- You might try another browser. The problem could be browser-related.
- You can always come back later. Contact your Internet service provider or webmaster. However, you might need to go for a cup of coffee. The error could be fixed by then.
Developers: Solution
Developers have a different point of view than consumers. It is possible to fix the 502 error for web managers. Here are some solutions for the 502 error for developers.
- You can trace-route or ping test the IP address to determine if the upstream server can be reached.
- To verify that the domain name is correctly resolving, use the DNS test tools
- To determine if a specific error is being thrown at the server, check the error logs of the website or server.
- Temporarily rename the “wp–content/plugins” folder on WordPress sites to eliminate plugins being a possible reason for the error.
- For any indications of blocked connections, check the firewall logs.
Closing word
The 502 bad gateway error, which is one of many possible errors on a website or server, is not the most serious. It is still a problem.
It may be fixed quickly and efficiently but it could indicate more serious issues that could lead to greater problems in the future. This is why it is worth investigating further when it occurs.
