Good morning
I have a problem with loomio docker environment in my local network and it’s seems that it’s a docker problems.
This is my network configuration:
172.16.0.15 is my apache reverse proxy server (fixed IP)
172.16.0.85 is my vm (ubuntu server 14.04 LTS) who host loomio (fixed IP)
172.17.0.xxx is loomio-docker in the host 172.16.0.85
172.16.0.15 can contact and speak with 172.16.0.85 (loomio works on port 80 and 443)
the network config on the host:
