Summary

Azure's 502 Bad Gateway error indicates that the Azure Application Gateway receives a request with a 502 status code, meaning the gateway does not recognize the request. This typically occurs when the gateway is unable to perform a network check. You must verify the specific Azure portal settings, such as the gateway address, the IP address on the Azure portal, and the IP addresses on the Azure portal for the gateway. If these settings are incorrect, the issue may be due to incorrect configuration. Check that the gateway is correctly defined in the Azure portal, ensuring it is assigned to the correct IP address. Ensure that the gateway address is correctly set to the specific IP address associated with your application gateway in the Azure portal. If the IP address configuration is wrong, update the gateway to the correct address in the Azure portal.
