The problem was, that if we did not specify listen [::]:80 to every server declaration, nginx would fail to start. Naturally, because one listen declaration would open and AF_INET6 and another one would try to open AF_INET by default. As correct dualstack OS, AF_INET6 would also listen on AF_INET thus causing "98: Address already in use".

What I would suggest is, if Nginx is compiled --with-ipv6 that it listens by default on AF_INET6. Another thing speaking for this is that this is how ipv6 enabled programs should work. Operate on ipv6, and let OS handle ipv4 to ipv6 mapping.

Sorry,

-    listen  [::]:80 default ipv6only;
+    listen  [::]:80 default ipv6only=on;
