    I keep getting a 504 Gateway Timeout Error http://prntscr.com/o1u82u

    Steps to Reproduce Error:

    After entering email and hitting the click the Subscribe Button on our Blog coinrevolution.com http://prntscr.com/o1u9fe, I am redirected to
    https://coinrevolution.com/?na=s , which I believe is a thank you page , however, I do not get nothing but a 504 Gateway Timeout Error http://prntscr.com/o1u82u.

    What could be the issue?

    From NGINX Error LOG

    /home/forge/coinrevolution.com/public/pt/wp-admin/admin-ajax.php (No such file or directory)” while reading response header from upstream, client:, server: coinrevolution.com, request: “GET /pt/wp-admin/admin-ajax.php HTTP/1.1”, upstream: “fastcgi://unix:/var/run/php/php7.0-fpm.sock:”, host: “coinrevolution.com”


    Hi, the missing file reported (admin-ajax.php) is not used by our plugin, hence that is another error not connected to newsletter. Probably that error is due to the prefix /pt/, maybe added by a multilanguage plugin.

    You should try to find out an error related to the url https://coinrevolution.com/?na=s which is an action url by newsletter which called directly works perfectly, giving back “invalid” which is correct.
    I suspect you have problem with the mailing system. Check from status panel if your blog is able to send emails.



    Hello Stephano, I resolved my error by updating my PHP Version from version 7.0 to 7.3
