[Alparslan]

my docker deamon completly disable ipv6 so nginx also sould be fixed

nginx: [emerg] socket() [::]:8081 failed (97: Address family not supported by protocol)
nginx: configuration file /etc/nginx/nginx.conf test failed

grep '::' data/conf/nginx/*
data/conf/nginx/dynmaps.conf:  listen [::]:8081;
grep: data/conf/nginx/includes: Is a directory
data/conf/nginx/listen_plain.active:listen [::]:80;
data/conf/nginx/listen_ssl.active:listen [::]:443 ssl http2;
