Hi Alex and Anton, it's been a long time since I posted here, but it's nice to be starting strategy development again.
My current (simple?) problem is not being able to connect OQ v3.7.1 to DC 3.1.0 on my Win10 desktop. As you know, I've been able to connect the same OQ to DC before, even remotely from desktop to AWS DC server through firewalls, etc. So I apologize for not being able to get them to connect to each other on my local desktop (which should be simple in comparison). But they won't connect.
I think I have the ports set up correctly (both the default 3008), and I have verified that DC is listening on 3008 (with netstat). I also searched the forums here for an answer, but couldn't find anything on connecting OQ to DC. So I'm posting here to leave a track record in case someone else (like me!) ever has the problem again.
Here is the relevant info
DataCenter v3.1.0 and OpenQuant 3.7.1 x64 are
- both running on my desktop (Win10x64).
- both configured to use port 3008, with unsecured channel
- "Netstat -a" shows DC is listening on port 3008.
But OQ will not connect to DC.
Here is the OQ provider error, saying it can't find the DC service on port 3008.
System.Runtime.Remoting.RemotingException: Requested Service not found

Any ideas on what I'm doing wrong? Thank you.
(PS, both programs seem to run fine on Win10, even after all these years. Great software!)
