Hi
I'd installed a reverso proxy apache on my local network (Ip 172.16.0.15)
I have a VM with loomio on docker (IP of the VM 172.16.0.85, and docker use 172.17.0.xxx ip on this VM)
this is my loomio.conf file on my reverse proxy server:

Loomio use nginx web server with let's encrypt CA certificate.
Loomio receive the let's encrypt certificate without any problems.
loomio works with my url htts://loomio.phimeca.com
but in the logs of loomio, i have this error:
| Code: | nginx_1 | nginx.1 | 2016/06/01 07:19:04 [error] 41#41: *13 connect() failed (111: Connection refused) while connecting to upstream, client:172.16.0.15, server: loomio.domain.com, request: "GET /client/0.20.4/app.min.css HTTP/1.1", upstream: "http://172.17.0.4:3000/client/0.20.4/app.min.css", host: "loomio.domain.com", referrer: "https://loomio.domain.com/d/xPfHy1Rh/test-"
nginx_1 | nginx.1 | 2016/06/01 07:19:04 [warn] 41#41: *13 upstream server temporarily disabled while connecting to upstream, client: 172.16.0.15, server: loomio.domain.com, request: "GET /client/0.20.4/app.min.css HTTP/1.1", upstream: "http://172.17.0.4:3000/client/0.20.4/app.min.css", host: "loomio.domain.com", referrer: "https://loomio.domain.com/d/xPfHy1Rh/test-"

It's seems to be a problem of communication between my apache reverse proxy server (172.16.0.15) and the loomio in docker (172.17.0.4 port 3000) host by my VM 172.16.0.85
how can i solved this problem.
Thank you for your help |

it seems that nginx can't connect to the backend server.
Check if you can open the url in a brower from the machine on that nginx is running. |

Thank you for your help
i can't open the url 172.17.0.4:3000 with the local browser, and also to none of all dockers.
but my host can ping all docker containers
if i write the url "localhost" i have this message: 503 temporary unavalaible form nginx 1.9.12
but from another computer https://loomio.domain.com always works  |

| Check your firewall / iptable rules. |
