I am having a similar error.
My credit card feed has not updated since the 28th of October (12 days), when I try to update or re-add the account, I get the following error.
Looks like the connection to 28 Degrees Mastercard (AU) isn’t available right now.
Try again in a few hours. (102)
I have spoken to my credit card company and they do not believe there are any issues with my account on their end.
