We don't want you to feel this inconvenience. Please know that helping you connect your Santander bank account to QuickBooks Self-Employed (QBSE) is my priority, @Andrew Clarke62. 

Here are some reasons why you're getting errors when reconnecting or reauthorising your bank account to QuickBooks Self-Employed (QBSE):

• The bank recently made some changes with their security feature or connection.
• Log in credentials set up in QBSE don't match with the online banking login.
• QBSE is unable to connect to your bank's website.

In the meantime, try connecting your bank account to an internet browser. This helps us isolate if you're only having this error from the mobile app. 

Check out these steps:

1. Go to this link: QuickBooks Self-Employed and provide your credentials to log in to your account. 
2. Click the Gear icon and choose Connect bank.
3. Select the Connect another account button to add another bank or credit card.
4. Search for the name of the bank. Sometimes a financial institution will have multiple bank names or they might have different types of accounts but choose to only release one website for connection to QBSE.
5. Follow the prompts to finish adding your bank account. 

Also, some banks require additional security steps before you can connect your account. Reach out to your bank if you need help connecting your account.

Here's more information about adding your bank and credit card accounts in QBSE on a web browser, On an iPhone or iPad (iOS), or a phone or tablet with android: Connect bank and credit card accounts to QuickBooks Self-Employed. 

Once you've added your bank account and pulled up your latest transactions, check out the following article on how to put them to the right SA103F categories, so you can claim allowable expenses for self-employment: Categorise transactions in QuickBooks Self-Employed.
