I just updated to the latest Google Checkout Patch. Now, I am getting an email from google stating: "We've made several unsuccessful attempts to send order notifications to your notification callback URL, As a result, you aren't receiving order status, risk, or other notifications."
I went ahead and looked at Google's Integration Console and found the exact error:
"We encountered an error trying to access your server at -- the error we got is Send failed with code: 401. Response body was: Failed to Get Basic Authentication Headers"
Any idea on how to fix this problem? Thanks in advance!
PS: I have only gotten this error after the update.
