Also, my domain that I used in WORDPRESS_URL triggers a 502 Bad Gateway status

should I be doing anything in nginx to get this fixed?

port 8080 is not open anywhere, should that port be listening?

Yes. If you are running Unit having following conf:

...
"listeners": {
    "127.0.0.1:8080": {
      "pass": "routes/wordpress"
    }
 }
...

then port 8080 should be listening:

% lsof -nP -iTCP -sTCP:LISTEN
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
unitd   257625  xim   31u  IPv4 959979      0t0  TCP *:8080 (LISTEN)

I had to run the unit configurations again (curl -X PUT --data-binary @wordpress.json --unix-socket /var/run/control.unit.sock http://localhost/config)

now I'm getting a new error ERR_INVALID_REDIRECT

curl -I https://something.org/
HTTP/2 301
server: nginx/1.26.0

the /wp-login.php works,
but I was hit with a (413 Content Too Large) error when trying to login,
I removed "max_body_size" from wordpress.json and "client_max_body_size " from nginx.conf

still not able to load the front page, must be some nginx misconfiguration in default.conf

visiting a blog post I am getting the error x-unknown-content-type ns_error_redirect_loop

nginx: [emerg] "upstream" directive is not allowed here in /etc/nginx/conf.d/default.conf:1

@wp-coin the article is 4 years old now. What is the end goal you want to achieve? My thinking is there might be an easier way to get there than debug a script that uses and assumes the state of things as of 2020
