I've used ISO Latin 1, UTF 8, ASCII. All with the same results. Not sure if this would help but it sits on the Downloading... Import transactions in OFX format for about 3-5 minutes then comes back with that error.

Using the exact account number as the response with the -S004 also tried changing version to 1900, exact same result.

When trying to connect to my bank to download the OFX file I get a response back from the bank showing my account numbers which tells me I am logging in successfully. But it never comes back with a response. I've also tried using different account numbers and account numbers without the extensions ...
