Server error when proxy-le is contacted by swarm listener

[qnm]

I'm unable get the default stack (from the README) working on my swarm.

My swarm listener is generating the following URL but when calling le-proxy this results in an error.

# docker logs 7264ba4a0061
2017/04/19 12:52:23 ERROR: Get http://proxy-le:8080/v1/docker-flow-proxy-letsencrypt/reconfigure?distribute=true&letsencrypt.email=dev%40digivizer.com&letsencrypt.host=whoami.dgvz.net&port=8000&serviceDomain=whoami.dgvz.net&serviceName=whoami_whoami&servicePath=%2F: dial tcp: i/o timeout

Here's what happens when I manually call proxy-le with my configuration:

docker exec  7264ba4a0061 wget -qO- "http://proxy-le:8080/v1/docker-flow-proxy-letsencrypt/reconfigure?distribute=true&letsencrypt.email=to dev%40digivizer.com&letsencrypt.host=whoami.dgvz.net&port=8000&serviceDomain=whoami.dgvz.net&serviceName=whoami_whoami&servicePath=%2F"
wget: bad header line: <title>Error response</title>

This resulting logs on the proxy-le image are:

INFO:letsencrypt:request for service: whoami_whoami

Any ideas? Have I mis-configured something?

Could you provide your compose files please ?

@n1b0r Hey mate. Restarting my docker daemon appears to have fixed the issues...

I was using the reference docker-compose.yml as per the README.
