Post From: Sierra Chart Connection Error - DTC Socket - Windows 10061

Hello,

I ran through two weeks of evaluations without any issues. I just signed up to Sierra Charts and the second day in a row now I'm having connection issues. I don't think it's on my end as I was running the SIM for two weeks downloading data. I'm also going to 'Send for Analysis'.

I would also like to add that this appears to be very intermittent as I just check this and was able to get SC to connect.
