https://wiki.debian.org/CommonErrorMessages/ArgumentListTooLong (last
modified in 2009) says that that happens when execve() "is unable to
fit the supplied argument list and environment into the 128K buffer".

Does "ps -ef" (possibly "| grep nginx") show the arguments involved?

And, with the right permissions,

wc -c /proc/*/environ 2>/dev/null | sort -rn | less

can show you the size of each process environment that you can read. If
you know the process id (PID) involved, you can just "wc -c" that one
directly.

That might hint at whether there is actually something very big involved,
or whether something else has gone wrong and the wrong error message is
being reported.

Good luck with it,
