IP visitor comments is exactly like my IP droplet. So I can not cut off the spammers by their IP

If this block proxy_set_header X-Forwarded-For $ proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $ scheme;

is added to

location ~ \ .php $ { fastcgisplitpathinfo ^ (+ \ php…) $ (*.); root $ rootpath; include / etc / nginx / fastcgiparams; fastcgipass 127.0.0.1:9000; fastcgiparam REMOTEADDR $ httpxrealip; fastcgiindex index.php; }

all * .php starts to work! But IP is not transmitted at all, there is an empty space in site page where is to be output IP.

Are you using a reverse proxy? Did you check the access logs?

@dvolob

How was your Droplet setup? Did you use a one-click image or did you install all software yourself? We need to know more about how your Droplet was setup before we can help.

To me, initially, it seems like you’re using a reverse proxy and that correct headers are not being sent, so when WordPress queries for the visitor IP, it’s reverting to the server IP as it can’t determine the real IP.
