Woocommerce time out with Atandra/T-hub

Our store, http://www.analyticalgrammar.com, uses Woocommerce for shopping, and Atandra/T-hub for shipping & labeling, plus flowing to quickbooks.
We just upgraded our store to Woocommerce from Magento last week. We’ve noticed that we’re having “operation time out” issues when T-hub tries to reconnect to Woocommerce and report info back to the website. Most of the info gets there, but it takes FOREVER.

When we ship, the tracking numbers and the “change this order to COMPLETE” gets sent back to WooCommerce. It’s that communication that is getting hung up. I have a log I can provide that shows the “operation time out.” Atandra has checked everything on the thub side. Since the info is (for the most part) reaching WooCommerce, their settings are seem correct, and they are pointing back to WooCommerce. Any suggestions?
