That says that the user you run as cannot open that file.

ls -ld / /var /var/log /var/log/nginx
ls -l /var/log/nginx/error.log

You may need a "-Z" in there too, if you have some extra security enabled.

Does your user have permission to write the current error.log file;
or to create a new one? If not, do whatever it takes to make that possible.

You do mention some "chmod" commands below, but none that refer to this
directory or file.

That is harmless; if you intend to run as non-root, you can remove that
directive from the config file.

That suggests that your user can read /etc/nginx/nginx.conf, but cannot
read /etc/nginx/conf.d/default.conf

"ls -ld" or "ls -ldZ" every directory from the root to that one.

Perhaps there is something there that shows why you are blocked.

777 is possibly excessive; but if it works for you, it works. If you
don't have "x" permissions on /etc/nginx/conf.d, though, you probably
won't be able to read the default.conf file within.

Do you do that as the same user/group that you run nginx as?

Good luck with it,
