gallery urls show up as 

https://site.com/:///gallery/image/39-20190729_185629jpg/?context=widget

and some of them can't be viewd when i turn modpagespeed on.

Otherwise it's fine

server {
    listen 80;
    listen [::]:80;
#    pagespeed off;
    error_log /dev/null;
    server_name www.site.com site.com;
    rewrite ^ https://site.com$request_uri? permanent;
}
server {
    listen 443;
    listen [::]:443 ssl http2;
#    pagespeed off;
    error_log /dev/null;
    include /usr/local/nginx/conf/openssl.conf;
    server_name www.site.com;
    rewrite ^ https://site.com$request_uri? permanent;

    root /home/site/public_html;
    set $no_cache 0;
    index index.php;
    location / {
        try_files $uri $uri/ /index.php;

    include /usr/local/nginx/conf/cache.conf;
    location ~ .php$ {

        include /usr/local/nginx/conf/fastcgi_params;
    }
    location ~^(/page/).*(\.php)$ {
        try_files  $uri $uri/ /index.php;
    }

So when you enable the pagespeed module for Nginx (based on your config I'm assuming here), it breaks the URLs, but they work fine otherwise?

You should probably get in touch with the developers of the pagespeed module about that issue: https://github.com/apache/incubator-pagespeed-ngx
