Description

When a container is connected to an overlay network, connections to published ports on the host get closed without any reply.

Reproduce

  1. docker swarm init
  2. docker network create --attachable --driver overlay my-ovl
  3. docker run -d --name nginxtest --network my-ovl --publish 8080:80 nginxdemos/hello:plain-text
$ docker exec nginxtest curl -Ss localhost
Server address: ::1:80
Server name: f369a2b56db6
Date: 10/Feb/2026:21:45:16 +0000
URI: /
Request ID: 050aaa199778336fd61d3b4b32b69855
$ curl -Ss localhost:8080
curl: (52) Empty reply from server
$ docker exec nginxtest curl -Ss host.docker.internal:8080
curl: (52) Empty reply from server

Expected behavior

Both curl commands to port 8080 complete successfully.
