There are a few reasons why you’re getting error 101, claus1867.
Banking error code 101 usually means that the bank's website is experiencing technical difficulties, undergoing maintenance, or there is a server issue with the data transfer between QuickBooks and the bank's website. Here are a few steps that we can check and try to fix it the issue:
If you don't see any sign of a problem or maintenance on your bank or credit card's website, you can try to manually update your account within QuickBooks. To do this, go to the gear icon > Bank accounts, and select Refresh All at the top of the bank list.
In a new tab or a different browser, let's sign in to your bank's website to see if you can get in without any errors.
If you're able to sign in successfully, look for a message, notification, or alert from your bank indicating that something isn't working. Also, let's make sure that you can see the account summary, account history, and account transactions without any problems.
I check for further details about First Direct bank and our engineers are still gathering data why some users are unable to reconnect their bank. I'd also suggest getting in touch with our Customer Support Team so if there are any updates we can keep you posted via email.
