Post From: Issue with conecction to historical stock data

I tracked this down. Sierra Chart is trying to connect to ds01.ddfplus.com
And when I enable this to come through my firewall, historical daily stock data loads fine again.
If you do have a range of IP addresses that this will map to, by all means let me know so I can specify them
in my firewall rules (like I do with all other Sierra Chart IP addresses.
Failing that, I can figure out a work around for myself (it will involve some programming),
but I'm guessing I'm not the only person operating behind a firewall, and perhaps, unlike me, some
users may need to involve a system admin to get through a company firewall.


Not sure exactly when this problem started, noticed for the first time today.
Attempting to update a DAILY (no problem with intraday data) stock chart, get "HTTP error when downloading from SC external historical data service. Status code: 0."

I was able to work around this by temporarily disabling my firewall, but that's not an acceptable solution.

I have always used these firewall settings with Sierra Chart (for many years), allowing connections to the IP addresses indicated in your documentation.

My guess is that you have recently changed how you are hosting your historical daily data, and it's not coming from
historicaldata.sierrachart.com as indicated in the documentation.

Haven't had time to fully investigate, but my preliminary look seemed like you might be hosting this on AWS now. If so, is there some new range of IP addresses that needs to be let through the firewall? Or is there a domain other than historicaldata.sierrachart.com that I need to let through?
