Aramex Plugin not calculating shipping

Hi there,

I’m supporting a client’s website. They said that today, all of a sudden, the plugin was unable to calculate shipping.

I went about updating plugins, disabling all related plugins, the issue persists. What actually happens is that when I go to Proceed to Checkout after filling out the billing information (shipping address, etc) it loads the following page for a split second (things seem glitchy, fields are out of place), then bounces me all the way through to the selected Payment Gate, without calculating and including the delivery fee.

When I go to the order section and try to manually calculate the shipping fee, it spits out the following errors:

Both of these locations exist and they even show up on past orders that have been completed without issue.

As I mentioned, nothing has been changed on the site and nothing has been updated recently, this just happened randomly today.

I checked the geolocator and relevant settings in the global section, everything seems to be in order.

Would you have any idea how I could fix this please? Also, is there any specific Woocommerce version that this plugin is supposed to be compatible with?
