Hi,

When you receive the error message "The account bank (101401) is archived" in Odoo while trying to connect a bank account, it means that the linked account in your Chart of Accounts is inactive or archived. Odoo does not allow operations involving archived accounts, so to resolve this, you need to reactivate the account. Go to Accounting > Configuration > Chart of Accounts, switch the filter to include archived records, search for account 101401, and click "Unarchive". Once unarchived, the system will allow you to proceed with linking the bank account without any errors.

Hope it helps.
