WiscWeb - WordPress UW Theme - 502 Bad Gateway

This document will provide you with information on what the 502 bad gateway error looks like, what it means, and what you can do about it.

Example of Bad Gateway error

Issue

The 502 Bad Gateway error is shown when a Denial of Service (DoS) attack is suspected. Typically when a user sees this issue, it is because they have attempted to make too many updates on their site in rapid succession, thus flooding the WiscWeb service with so much traffic that it is suspected to be malicious in nature, like a bot attack. The system will then block the requests, as a security measure.

Resolution

This issue arises because the traffic is all associated with a single IP address. Therefore, changing your IP address can help resolve it. The easiest way to do so would be to disconnect and then reconnect to VPN.

These options can also help resolve the issue:

  1. If a single update is needed to be made, please wait at least 10 minutes before attempting to re-publish or save your changes. This should be long enough to allow things to normalize.

  2. If multiple updates are needed, please space them out by several seconds to avoid triggering this response.
