After PR #270 the VPC-LR-wide 0.0.0.0/0 -> IGW static route is no longer installed implicitly at attach-internet-gateway. Subnets whose effective route table lacks an internet-bound route get an OVN drop policy at SubnetEgressPriorityDrop (1100), which kills LB target reply traffic before un-DNAT can fire and stalls the LB internal-client probe until job timeout. Add the standard AWS pattern: describe-route-tables -> create-route 0.0.0.0/0 -> IGW. This fires vpc.add-igw-route + vpc.ungate-subnet-egress, removing the drop policy and installing a reroute policy at SubnetEgressPriorityIGW (1000).
