In my case, I was using nginx with a load balancer, so I had to update the haproxy config to increase the server timeout timeout server 3000s – Pomona

Answer 1

Depending on the kind of gateway you have you should use something like:

proxy_read_timeout 600s;

Check docs: http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_read_timeout

I found that scalescale.com/tips/nginx/504-gateway-time-out-using-nginx has some additional timeout settings mentioned. That could also be helpful in this regard. – Threedimensional

Well I tried to answer the question first. Other options mentioned there are not about nginx or not about fixing error 504 (except *_connect_timeout porbably... but that's rather about network connection issues). – Isotope

Yes, I'm aware of that and I also found your answer helpful a good deal to me. Just thought that the additional info might help others as well .) – Threedimensional

do you need to put 's' to the time ? proxy_read_timeout 60s; – Rode

@DavidLin, you are right, though seconds are default, measurement units should be added per nginx.org/en/docs/syntax.html – Isotope

Make sure to create a new file and add it to /nginx/conf.d/ folder rather than editing /nginx/nginx.conf folder directly. This is better for portability and to easily see and edit past changes. – Linehan

If it is a fastcgi timeout error, then you need to increase the fastcgi_read_timeout.

# /etc/nginx/conf.d/example.com.conf
server {

    location ~ \.(php)$ {
        fastcgi_pass unix:/var/run/php74-example.com.sock;
        fastcgi_read_timeout 300s;

error log) upstream timed out

# tail -f example.com.error.log
2020/12/29 14:51:42 [error] 30922#30922:
