error 504

Hi,
It gives an error 504 every time you subscribe to the newsletter or try to send a test letter.
When you subscribe to a newsletter, the data goes into the newsletter, but the site falls into error 504, each time.
The site writes that the problem is in the wp-admin/admin-ajax.php file, but this is the base wordpress file.
How to fix it?

Hi,

I am guessing that you are using Nginx web server? Something is blocking normal execution of Ajax calls in WP. You should check your webserver error logs to see what exactly is happening
