WooCommerce 504 Errors

I have a huge Woocommerce store, and have used Ordoro for quite some time. Recently Ordoro times out during a synch and tells me to contact support. When I contacted support they told me that my problem was due to too much data and timeout errors.

I contacted my rackspace support and was told to up the memory and execution timers of my PHP-FPM.

So I bumped

default_socket_timeout = 1200 (from 300)
memory_limit = 256M

And still I’m getting stuck while all products import, none of them update. Does anyone have a similar issue or know of a way to increase the limits at which I can process these large volumes of data using ordoro?
