Unexpected Server Error When Creating Shipping Label

Hi,

For the past 2 days I’ve run into this error when I am trying to purchase a shipping label through Woocommerce.

Quick Breakdown:
1. Customer places an order on my website.
2. I get the order, go to the order’s page in “Woocommerce>Orders”
3. I click the button that says “Create Shipping Label”
4. Origin Address is good, Destination address is good, Packaging is good.
5. When I click “Use these packages” and it moves to the 4th step “Shipping Rates” an error pops up that says “Unexpected Server Error.”

There’s a button that says “Retry” next to the error, but if I click it, nothing happens. If I click it a bunch of times, it just keeps loading the error over and over again.

I’ve disabled Jetpack, uninstalled jetpack, reinstalled jetpack, reenabled jetpack and still the error persists.

I’ve gone into troubleshooting with my site, disabling every plugin, going to a default theme, then enabling the woocommerce plugin + woocommerce services + jetpack and tried to complete the purchase and print a shipping label and still the error pops up.

Just a few days ago everything was working fine. I have no idea what caused this issue. All of my plugins are up to date and everything is working properly.

Customers are still able to place orders, but I can’t print out USPS labels to ship their packages so this is very frustrating.

Please help!
