ARR Proxy Returns HTTP Error Code 502.4
Issue: The ARR Proxy server could return the HTTP Error Code 502.4 when any of the Management Servers (HServers) are not available.
The Health Status of all the HServers in the Server Farm may be set to Unhealthy because the congured Health Tests have failed.
Resolution: To correct this:
1 Log in to the ARR Proxy Server and launch the IIS Server Manager.
2 Select the Server Farm you created and on the right-hand pane, select Monitoring and Management.
3 Select the HServers and in the Action pane, select Set Server as Healthy.
4 If the load on the HServer is high then try to increase the interval and time-out values in the Health Test feature
Enabling SSL Ooading on Proxy
Load Balancing is only supported in HTTPS setup. For debugging, if you want to see the Management Server (HServer) response in
Wireshark capture, then you can change the HServer-Proxy communication to HTTP.
1 Log in to the ARR Proxy Server and launch the IIS Manager.
2 Double click the Routing Rules feature and select Enable SSL ooading setting.
3 Enable both HTTP and HTTPS binding in the website on the HServer machines and do not select Require SSL in the SSL Settings.
