Buy Shipping not working for me, specifically UPS

I have tried to buy shipping a few times this morning (from the US) and it keeps telling me “Error occurred while purchasing a label, please try with different ship method”. Obviously, I tried a different method. I’m only having this problem with UPS but on one Merchant Fulfilled order, it only gives me UPS and FedEx as options. The FedEx is $19.98 while the UPS is $6.14, so it seems stupid to have to use the FedEx option. This particular shipment doesn’t show USPS as an option (Yes I have all shippers selected as options). I can wait an hour or two but this is supposed to go out today.

Also, every time I hit the “ship” button with the UPS option, I get an email that I’ve created a new UPS account. Every single time. So I now have at least 6 new UPS accounts.

I’m assuming it’s a glitch but if it doesn’t go away by this afternoon and this shipment has to go out for metric’s sake, what would you do?

Thanks!
