An unknown error has occured E01

  • About 20 seconds after submitting a review an error is returned via a JS alert, even though the submission is successful and the review enters the database.

    The error is as follows:
    An unknown error has occured E01

    In the chrome developers console I can see:
    504 Gateway Time-out
    Failed to load resource: the server responded with a status of 504 ()
    Failed to load resource: the server responded with a status of 502 ()

    In the nginx logs on my server I can see:
    2017/04/05 11:49:56 [error] 4624#4624: *1538 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 79.xxx.xxx.xxx, server: mydomain.ie, request: “POST /wp-admin/admin-ajax.php?action=wpcr3-ajax HTTP/2.0”, upstream: “fastcgi://unix:/var/run/php/php7.1-fpm.sock”, host: “mydomain.ie”, referrer: “https://mydomain.ie/testimonials”

    It is a PHP 7.1 server and everything else runs fine.

    Any ideas??

    Thank you.
