asterisk (*) should be a wildcard for IPv6 [::] and IPv4 0.0.0.0 not Ipv4 only.
This is especially important since you stopped adhering to the global configuration and instead defaulting to ipv6only=on.
So users configure the system to do automatic dualstack, writing a dual stack address and nginx binds just IPv4 only.
This broke the dual stack support of more or less all the software that bundles nginx like gitlab and a lot of smaller webservers.
People especially on Linux are expecting dual stack to work out of the box without additional configuration.And since there is a fallback to IPv4 many even do not recognize that they have a problem.
