> where do I raise the timeout on nginx?

For my nginx setup it was enough to set the timeout to 10 min (600 seconds).

### **PHP FPM config**

Add this line:

```auto
request_terminate_timeout = 600

```

Location of the config on my system: `/usr/local/etc/php-fpm.d/nextcloud.conf`

### **nginx config**

Around/below the line `fastcgi_pass php-handler;` add this line:

```auto
fastcgi_read_timeout 600;

```

Location of my nginx conf: `/usr/local/etc/nginx/conf.d/nextcloud.conf`
