This can be frustrating for users who are looking to access content or manage their newsletters on the platform. The error can be caused by various issues such as server overload, connectivity problems, DNS issues, or even browser-specific errors.
Addressing this error usually involves a few troubleshooting steps. Users might start with a simple page refresh or delve into more complex solutions like checking DNS settings or contacting Substack support for assistance. It’s essential to approach the problem methodically, as the issue might resolve itself or require a specific action depending on the underlying cause of the error.
Understanding Error 502
When one encounters a Substack Error 502 Bad Gateway, it indicates a disruption in communication between servers. This section helps shed light on what this error means and the typical reasons it occurs.
What Is Error 502 Bad Gateway
Error 502 Bad Gateway is an HTTP status code signifying that one server on the internet received an invalid response from another server. Substack users encounter this error when the platform’s server, acting as a gateway or proxy, fails to get a valid response from the upstream server to fulfill a request.
Common Causes of Error 502
The causes of an Error 502 can vary, but two common reasons include server overload and network errors. Server overload happens when there’s an unexpected surge in traffic or if the server is running low on resources. Network errors might occur due to issues with DNS servers or faulty networking equipment.

Advanced Troubleshooting Techniques
When Substack users encounter a 502 Bad Gateway error, advanced troubleshooting is sometimes required. This section will explore how to address DNS issues, check for server overload, and identify CDN problems that could be contributing to the error.
DNS Issues and Solutions
Problems with the Domain Name System (DNS) can prevent access to Substack, which may result in a 502 Bad Gateway error. Users can attempt to flush their DNS cache by accessing their operating system’s command prompt and using the ipconfig /flushdns command. Changing the DNS server to a public DNS like Google’s 8.8.8.8 or Cloudflare’s 1.1.1.1 might also resolve the issue.
Check for Server Overload
Server overload is another potential culprit for a 502 error on Substack. Website administrators should monitor their server loads and resources carefully. If they detect high traffic spikes or resource depletion, they may need to consider scaling up their server capacity or implementing rate limiting to maintain stability.
Content Delivery Network (CDN) Problems
A misconfigured or malfunctioning CDN can lead to a 502 error. Website administrators are advised to check their CDN settings and error logs. If the problem lies with the CDN, they might need to purge the cache or temporarily disable the CDN until the issue is resolved. Contacting the CDN’s support team for assistance is also a prudent step.
