![]() src=CoreDNS-IP dst=NODE-IP sport=53įor some reason all DNS resolving connections to the authentication service are going through the same port 13217 despite the fact that the connection is already defined as unreplied. There are several reasons why, mainly because they don't contain any connection establishment or connection closing most of all they lack sequencing. Udp 17 20 src=NGINX-IP dst= 10.0.0.10 sport=13217 dport=53 UDP connections are in them selves not stateful connections, but rather stateless. If that were not the case, any connection from outside trying to reach the LAN behind linux-routers eth2 interface would be SNATed to 1.1.1.6. On the node we can see UNREPLIED connection (conntrack -L) as following Removing LinkedIn connection requests is. The error is followed by addition error message: auth request unexpected status: 502 while sending to clientĪll requests to authentication service should succeed rejecting will send a rst instead of dropping that would keep the connection in a time wait SandriNenes at 13:13 1 Thanks Sandri, yes that would be a very good reason for using reject, however TIMEWAIT is a socket state dependent on a TCP packet getting as far as the network stack. This LinkedIn automation will automatically withdraw all your unanswered connection requests in a few seconds. The request is not being accepted by the Authentication service, the timeout is probable related to the connection establishing. ![]() ![]() To triage the issue we have added unique request id header that is logged on client, nginx access logs and authentication service. The issue could be solved immediately by simple restart of the container (the pod remains on the same node). There are intermittent timeout exceptions could not be resolved (110: Operation timed out) that are localized to very small subset of nginx-ingress-controller instances (typically one rarely two). We use external authentication service that is located outside of the Kubernetes cluster. Cloud provider or hardware configuration:.In this case i get the request to my internal vm from external originating source.Kubernetes version (use kubectl version): So here is my question, according to my knowledge of how NAT should work i should see request on the inside of my edge going towards my vm, where the source is the inside address of my edge, not the address of the original source. On the internal interface on our Edge i can see this when a request comes in: When the ATA attempts to communicate using the old IP address, the response is unreplied, and then if the UDP Unreplied timeout is greater than the Keep Alive Interval (and UDP Unreplied timeout is often set to 30 by default in consumer routers) a problem arises where the corrupted connection persists. ![]() In the connection tab I have alot of unreplied calls to the Comcast DNS servers. Sometimes even, it will say something to the effect of DNS Probe. On the external interface on our Edge i can see this when a request comes in: I am having an issue where alot of the time, my internet will start to go real slow or a page will take forever to load. We are allowing the traffic to flow through the firewall in the Edge to the destination through the DLR. We have a DNAT rule applied on the public interface on our Edge translating external ip to internal. We are using NSX 6.2, and we are experiencing some issues with NAT. The reply is arrived, the unreplied flag is gone, it means this UDP connection is in ESTABLISHED state for a small amount of time defined in your system.
