nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)

how to let it start please

Solution 1

just i deleted this line

listen [::]:80 default_server ipv6only=on;

from

/etc/nginx/sites-available/default and it works :D

Solution 2

nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)

From the error message this seems ipv6 is disabled on your server. Edit nginx default server configuration and changed it to listen on ipv4 only or enable ipv6.

listen 80 default_server;
# comment to disable ipv6
# listen [::]:80 default_server;
