Hi Mike Prest,

Thank you for posting in the Microsoft Community Forums.

I. Basic information and operational status of Azure Application Gateway/v2

Azure Application Gateway/v2 is an Azure-based application gateway service that provides features such as load balancing, SSL offloading, and Web Application Firewall (WAF) designed to improve application availability and security. However, any cloud service or infrastructure can be affected by a variety of factors including, but not limited to, misconfigurations, service failures, network issues, or external attacks.

Analysis of the “502 Gateway Failure”

A “502 Gateway Fault” typically indicates that a server working as a gateway or proxy is receiving an invalid response from an upstream server. In the context of Azure Application Gateway/v2, this can be due to the following reasons:

Backend service unavailable: If a backend service, such as a virtual machine, container, or web application, is not running or cannot respond to a request, Application Gateway may return a 502 error.

Configuration Error: There may be a problem with the configuration of Application Gateway, such as incorrect backend pool settings, incorrect HTTP settings, or authentication configuration issues.

Resource constraints: If the Application Gateway or its back-end service reaches a resource limit (such as a CPU, memory, or connection limit), this may also result in a 502 error.

Network issues: Network latency, packet loss, or routing issues may also affect communication between Application Gateway and its back-end services.

Service failure: Although uncommon, the Azure service itself can fail, causing Application Gateway to not work properly.

Resolution Steps

For “502 Gateway Failure”, you can try the following resolution steps:

Check back-end services: Ensure that all back-end services are running and can respond to requests.

Check Application Gateway Configuration: Double-check the configuration of the Application Gateway, including backend pools, HTTP settings, authentication, and so on, to ensure that all settings are correct.

Review logs and monitoring: Utilize Azure Monitor and other monitoring tools to view logs and performance metrics for Application Gateway and its back-end services to diagnose problems.

Check Network Security Groups and Network Policies: Ensure that Network Security Groups (NSGs) and network policies allow communication between Application Gateway and its back-end services.

Best regards

The Microsoft platform was down, not a config issue on my end.
