Hello and welcome to the Community, Mireia
We appreciate you reporting your issue with the bank connection.
Error 305 isn't an error code that we have listed on our common banking errors in QuickBooks.
If you are seeing a 350 error code instead, this means that we have lost connection with your bank account and the connection needs to be established for a further 90-day period.
If you don't see a prompt to re-authorise the connection from the Manage accounts page (on the web version of QuickBooks, click the Cog > Manage accounts) please contact our support team by chat or on 0808 234 5337 so that we can take a closer look in the background. Thank you.
