What Is Error 502 at Unisa?

Getting a “502 Bad Gateway” error message while trying to access the Unisa online resources can be frustrating.

This error 502 code means there is a communication issue between servers that is preventing the information you need from reaching your device.

This guide will explain the reasons behind the error, troubleshooting steps you can take, and how to get the help you need if the problem persists.

What Does “Error 502 Bad Gateway” Mean?

A “502 Bad Gateway” error indicates a communication issue between servers.

When you attempt to access a Unisa library resource, your request goes through a Web Access Management (WAM) proxy server.

This server acts as an intermediary, relaying your request to the resource server that holds the information you need.

However, if the WAM server receives an invalid response from the resource server, it throws a “502 Bad Gateway” error.

This can happen due to various reasons on either end, like temporary glitches, server overload, or even maintenance activities.

Is the Error My Fault?

In most cases, the “Error 502 Bad Gateway” is not caused by an issue on your end.

It’s a server-side communication problem between the WAM proxy and the resource server.

However, there are a few rare instances where your internet connection or browser settings might be contributing factors.

How Long Does the Error Typically Last?

The duration of a “502 Bad Gateway” error can vary. In most cases, it’s a temporary glitch that resolves on its own within a few minutes.

However, if the error persists for an extended period, it might indicate a more significant server issue that Unisa IT is addressing.

What Can I Do to Fix the Error?

These are some troubleshooting steps you can try when facing a “error 502 Bad Gateway” problem:

1. Refresh the Page: This is a simple yet surprisingly effective solution. A quick refresh can sometimes clear up temporary glitches.
2. Clear Your Browser Cache: Cached data can sometimes become outdated and cause display issues. Clearing your cache can help ensure you’re loading the latest version of the webpage.
3. Try a Different Browser: If the error persists in one browser, try accessing the resource using a different one. This can help identify if the issue is browser-specific.
4. Check Your Internet Connection: Ensure your internet connection is stable. A weak or fluctuating connection can sometimes lead to communication errors.
5. Wait and Retry Later: As mentioned earlier, these errors are often temporary. Wait for a few minutes and try accessing the resource again.

If none of these steps work, the issue is likely with the Unisa servers.

Can I Access Resources Offline?

Most Unisa library e-resources are not available for offline access.

This is because they require authentication and may contain dynamically updated content.

However, some resources, like downloaded PDFs or saved articles, might be accessible offline depending on how you obtained them.

How Can I Report the Error 502?

If the “Error 502 Bad Gateway” persists after trying the troubleshooting steps, you can report the issue to Unisa’s library technology support team.

They can investigate the problem further and provide updates on the situation.

Here’s how you can report the error:
