That's about the "nginx -V" field you've left blank.

Or not, bacause the answer is obvious unless you have very strange
background. Moreover, the documentation explicitly explains the
default for "max_conns", so this should be obvious regardless of
the background:

: max_conns=number
: limits the maximum number of simultaneous active connections to
: the proxied server (1.11.5). Default value is zero, meaning there
: is no limit.

If you for some reason think that only consequent connections are
allowed, most likely you are facing limitations of your backend.
