I’ve been using WP Migrate DB Pro and Vagrant for some time, but there has always been one aspect that has really annoyed me: when pulling from a remote server to my local environment, Media downloads would (very) often fail due to a 502 timeout.
I had always assumed it was an error on the remote server, until one day I was reading through my local log files (as one does) and stumbled across a Nginx configuration change that made everything work as it should.
I should note that my configuration uses Nginx and PHP-FPM, and it’s the configuration of the latter which is where the tweak needs to be made:
location ~ \.php$ {
...
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
...
}https://stackoverflow.com/questions/46205725/nginx-502-fastcgi-error
Where you configure how PHP files are handled, be sure to increase the buffers and buffer size — the defaults are too small to handle the amount of data downloaded by WP Migrate DB Pro.
With this simple change, I can finally work locally with WordPress and be sure my files are in sync with the remote server.
