How to correctly setup location block for Wordpress at /blog on existing site

I have installed Wordpress at the /var/www/html/wordpress and modified my sites-available file as shows:

server {
        server_name innerhealerchiropractic.com www.innerhealerchiropractic.com;
        root /var/www/html/;
        index index.php index.html;
        access_log /var/log/nginx/innerhealerchiropractic.com-access.log;
        error_log /var/log/nginx/innerhealerchiropractic.com-error.log;
        set $yii_bootstrap "index.php";
        charset utf-8;

location / {
        index  index.html $yii_bootstrap;
        try_files $uri $uri/ /$yii_bootstrap?$args;
        }

<^>location /blog/ {
        alias /var/www/html/wordpress;
        index index.php index.html index.htm index.nginx-debian.html;
        try_files $uri $uri/ /blog/index.php$is_args$args;

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }
    }
<^>
location ~ ^/(protected|framework|themes/\w+/views) {
        deny  all;
        }

location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
        try_files $uri =404;
        }

location ~ \.php {
        fastcgi_index index.php;
        fastcgi_split_path_info ^(.+\.php)(.*)$;
        set $fsn /$yii_bootstrap;
        if (-f $document_root$fastcgi_script_name){
            set $fsn $fastcgi_script_name;
        }
        include /etc/nginx/fastcgi_params;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

location ~ /\. {
        deny all;
        access_log off;
        log_not_found off;
        }

## other lines below unchanged as they are for certbot

I am getting a 403 forbidden error when going to https://innerhealerchiropractic.com/blog, and it shows in the access logs that way.

The main site is running yii, so I’m not sure what else I need to do to allow this access. Normally I’d allow my IP access in an .htaccess file but I don’t know how to set that up for this situation.
