Hi, milena-ratti-subacchi. Experiencing connectivity issues can be challenging, especially when linking your bank account to QuickBooks.
When you encounter Error 590 while attempting to connect your Wise Business Euro account to QuickBooks Online, it means that QuickBooks could not establish a connection due to an unexpected issue on the bank's end.
This can be quite inconvenient, but I recommend waiting a few hours before reconnecting your account. During this time, it’s also helpful to check your bank's status for any known connectivity issues and ensure your login credentials are accurate.
