Topic: Unable to load transactions from Fidelity Investments?

I just started using GnuCash and aqbanking. I've installed version 5.3 on Windows. I'm now trying to set up online banking with Fidelity Investments. I'm able to set up my user, download accounts, and successfully map them to accounts in GnuCash. I'm unable to download transactions. I get the following:

AqBanking v6.5.4.0stable

I searched the forum and saw others with the same problem, but no suggested workarounds. Where can I go from here?

Thanks.

Re: Unable to load transactions from Fidelity Investments?

I use KMyMoney, any my OFX direct connect to Fidelity is working fine.  I'm using url="https://ofx.fidelity.com/ftgw/OFX/clients/download"   Can you run wireshark or similar to see what is actually getting sent and returned?  That 400 error sounds like it might be a malformed HTTP request, as I think that error is coming from their web server, not from the OFX software.
