For the past couple days I have not been able to download transactions from First Internet Bank. Nothing had been changed on my end before this started.
There's no specific error code provided in Quicken (just "An error has occurred" in One Step Update Progress screen), but CONNLOG.TXT reports:

Additionally, OFXLOG.txt has the error message "Invalid FID sent in Request" but the FID value in the XML matches the routing number of the account/bank.
