Hi, When we run CDSW validate command on the problem worker we gut this message : [Validating networking setup] > Checking if kubelet iptables rules exist The following chains are missing from iptables: [KUBE-EXTERNAL-SERVICES, WEAVE-NPC-EGRESS, WEAVE-NPC, WEAVE-NPC-EGRESS-ACCEPT, KUBE-SERVICES, WEAVE-NPC-INGRESS, WEAVE-NPC-EGRESS-DEFAULT, WEAVE-NPC-DEFAULT, WEAVE-NPC-EGRESS-CUSTOM, KUBE-FIREWALL] WARNING:: Verification of iptables rules failed: 1 > Checking if DNS server is running on localhost > Checking the number of DNS servers in resolv.conf > Checking DNS entries for CDSW main domain > Checking reverse DNS entries for CDSW main domain > Checking DNS entries for CDSW wildcard domain > Checking that firewalld is disabled > Checking if ipv6 is enabled [Validating Kubernetes versions] > Checking kubernetes client version > Checking kubernetes server version -------------------------------------------------------------------------- Errors detected. Please review the issues listed above. Further details can be collected by capturing logs from all nodes using "cdsw logs". Is this related to the problem? Thank you, Rony
