What to do when I keep getting this error message from Wise: Something unexpected happened and we can't connect to Wise Business (Euro)?Try again in a few hours. (590)

Thank you for reaching out in this forum, Abundant. I'm here to help you resolve the error message you're experiencing while reauthorizing your bank with QuickBooks.

The error code 590 suggests there’s a connectivity hiccup between QuickBooks Online (QBO) and Wise. To resolve this, I recommend checking if your bank’s website is undergoing system maintenance or update, as that could be the cause of the issue. If everything looks fine on their end, you might want to give it a few hours and then try reauthorizing your bank account.

Moreover, if the issue persists, I suggest contacting Wise's customer care team. This way, they can provide additional detail about this error code and may offer some assistance on resolving this.
