Nginx 504 Error when trying to use PHPMailer

I’ve been trying to send an e-mail using PHPMailer but have been getting a “504 Gateway Time-out” error.

Did a bit of research and I think it’s because nginx is trying to use IPv6. I thought the solution was to try to make it use IPv4 was the solution.

Tried to do the following already: echo 'Acquire::ForceIPv4 "true";' > /etc/apt/apt.conf.d/99force-ipv4 echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf service nginx restart

Still getting the same issue and I can’t find anything else that I could try.

Hi @drcmanansala,

It’s impossible to pinpoint the exact issue without checking the error logs of Nginx. The problem could be a million things from permissions,ownership to a problem with the Nginx configuration preventing to work with PHPMailer.

I’ll recommend before you make any changes whatsoever, to check the Nginx error log and see the exact error you are getting.
