Support » Plugin: WP Mail SMTP by WPForms » Timeout Sending Emails

  • Resolved captaincrank


    Sometimes new order emails are not being received by us and our customers are not receiving their new order email confirmations. When I try to resend an email in Woocommerce, sometimes the email is sent but a 504 timeout error is produced with the error logged below:

    2021-08-08 22:55:48 UTC [apache][:warn] [pid 56678] [client 71.64.XXX.XXX:54300] Timeout waiting for output from CGI script /home/u888-hjcegfgoeccz/www/, referer:

    WP Mail SMTP Version: 3.0.2
    Woocommerce Version: 5.5.2

    Hi @captaincrank,

    Thanks for reaching out. The timeout issue is usually caused by a slow connection between your site and the SMTP host you’ve configured, and eventually, it reaches the fixed limits of the server and times out. You might need to contact your web host to look into the connection or switch to other available mailers.

    I hope this helps!
