Can't download historical and replay data

[User13]

I can stream live data, but unable to download neither historical (ES 12-14 for yesterday) nor replay data (ES 12-14 for last week).
I've reset instruments, deleted the .sdf file (because db reset would never complete), and restarted PC.
In trace log I see:

ERROR: Unable to connect to NinjaTrader data server (HDS11.NinjaTrader.com/31654): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

HDS11.NinjaTrader.com is pingable though

Hello User13,

I do not have any issues to connect to HDS11 on my end. I have also not seen reports from other customers so far.

Could it be you have software running on your computer that could be blocking NinjaTrader from connecting to the NinjaTrader server? Please terminate all other applications you have running and check again.

Please try a reset of your modem/router and check if this will make a difference.

I have a firewall, but there's nothing in the logs and disabling it doesn't help. It didn't prevent the downloads in the past and I haven't done any reconfiguration.

Can you please try a reset of your modem/router.

Do you perhaps have access to another internet connection to test if you can connect to the NinjaTrader server?

I cannot reset reset the modem until sunday.
Have just tried to connect to HDS11.NinjaTrader.com/31654 with a simple app which simply opens and closes a TCP connection and weirdly it succeeds, but NT still fails.

I have no access to another connection.

Can you please send me your log and trace files. Go to Control Center-->Help-->Mail to Support in NinjaTrader. Put 'Attn Jason, Can't download historical and replay data' in the subject field and enable 'Log and trace files'.

The problem seems to have been caused by my router, which I recently updated. Once connected directly to modem, connection succeeds.
Thank you for your time, Jason.
