Shiny proxy not working after latest docker upgrade



We have updated to the latest version of docker EE: Docker version 17.06.1-ee-2, build 8e43158

After the upgrade, we have followed the instructions:

Afterwards, we get the following error:

Status code: 500

Message: Failed to start container: java.util.concurrent.ExecutionException: org.apache.http.conn.HttpHostConnectException: Connect to [/] failed: Connection refused (Connection refused)

Is the following line: ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -D -H tcp://
not current anymore, or not working with the newest version of docker?




I’m experiencing the same issue with

Docker version 17.06.2-ce, build cec0b72
16.04.3 LTS (Xenial Xerus)


Changing ExecStart variable in the /lib/systemd/system/docker.service file fixed the issue for me.

ExecStart=/usr/bin/dockerd -H fd:// -D -H tcp://


I faced the same issue. Editing the /lib/systemd/system/docker.service as suggested by Luke_Singham fixed it. Thanks a lot!


Thanks @marekdabek for the report, @Luke_Singham for the fix and @Claas for the confirmation. I have updated the getting started guide at to be in line with the latest Docker versions.


Somehow my Centos 7 with Docker version 17.09.0-ce only works when the old setting was presented.
