The account refresh was stopped because your bank identified the query as automated and blocked it. As a workaround, please exclude all accounts from this bank from overall refresh under 'Settings' > 'Refresh Accounts' > ‘Refresh Interval: Accounts’ > set the interval to ‘Off’ for all accounts from the bank.
Then, wait for a few hours before manually refreshing the account again.

As a quick alternative, you can also change your IP address, for example, by restarting your router.
