Rescode: 499 observed during REST API calls from external applicationsSummaryWith inbound integrations, especially when API calls are received in huge quantities, the external application received a response code of 499 where the request does not reach the app nodes.ReleaseAll versionsInstructionsWhen there is a huge number of API calls received from external applications, the NGINX in the ADC v2 load balancer sometimes returns resocde=499. Reviewing the appnode localhost logs, we can see that the requests have not reached app nodes. This usually happens if the external client times out and closes the connection to Server (ADCv2 load balancer in this case). To investigate the root cause of this issue, please run the packet capture between Servicenow VIP and the external application endpoint IP, while replicating the issue. Raise a Support case with Servicenow and attach the packet capture, to investigate the root cause
