I'm getting an error message when I try to connect my Monzo business account. Anyone knows how to solve this?

Hi there, giuliat0909-gmai.

Can you tell me the exact error message when trying to connect your Monzo business account? This way, I can provide the correct solution to it.

In the meantime, let's try connecting the account on a private window. It is to isolate what causes the error message. You can use these keyboard keys to open one:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

If it works, we can go back to a regular browser and clear its cache. A piled cache can also be the reason for some unexpected issues on the opened pages.

We can also switch to a different browser like Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge.

Once connected, you can check this reference in categorising the transactions: Categorise and match online bank transactions in QuickBooks Online.

Let me know if there's anything that I can help. Keep safe!
