I also am encountering this issue. The rep I spoke with told me that on the initial attempt to reconnect the account, they should be able to see the attempt on their side and then enable "Quicken" access. I've tried disabling online banking for the account, refreshing the connections, etc..., but the representative isn't seeing the ping when I attempt to connect. I'm thinking they changed something in the protocol and Moneydance will need to update. I'll keep an eye on this thread for a fix.
I am in the same situation. I have also submitted a private request for help with an exact error message from Moneydance. I have updated to the latest version of Moneydance as well as updated to the latest MacOS - no luck.
Same problem. Syncing with TD Bank has been working fine for years, but as of their security upgrade over a month ago, I haven't been able to download transactions. Get this error: A communication or parsing error occurred. This could be the result of a network problem, a proxy error, or misconfigured server.
Error Description: java.io.IOException: HTTP Error:400 Bad Request.
I am using version 2017.7.1. I tried "Refresh" in Set up online banking. Doesn't help.
I am having the same problem. I called TD Bank and they claim they have not changed the OFX information. Note that there is a debug screen you can look at on TD Online banking and it will show you the last OFX request they got. It never shows anything.
Note there is a work-around. You can sign on to the online banking and pull your file by exporting it. The option is in the transactions page. This has continued to work all along and there is an option to do all accounts.
Still I would like IK to please fix this.
I'm sorry to say that after 6 weeks of communication both with my bank and with IK, I finally had to break down and download another money management program. I loved Moneydance and would have continued using it and telling people about it for years to come, but I manage all of the finances for our family and I thought the risk of error was too high without downloads.
I went with Quicken for now because that is who my bank supports. I will say though, that I LEFT Quicken to go to Moneydance after being beaten to a pulp by Quicken's upselling and persistent emails urging renewal (starting approximately 1 month after my purchase). Very frustrating company to do business with so I would be thrilled if Moneydance would work again so I could return to the peace and quiet that doing business with IK provides. :)
