Firewall blocks addresses during first login

[U1wq2]

Hello,

I’m having Problems with the DAQExpress V5.1. When I try to start up DAQExpress the first time I get the error 0x6AD7DF6F. I know that the Problem appears because DAQExpress tries to connect to some addresses from NI during the login but because of our Firewall, all the requests get blocked and DAQExpress won’t start. Now I would like to know which addresses DAQExpress tries to connect during the first login so that we can whitelist them.

Thank you for any help

This article lists the ports used by various NI product, please ensure those ports are not blocked by your firewall for them to work properly.

If DAQExpress usage is important, you might have to fight with IT to open up those ports in the firewall.
