Eucontrol won't launch - 23.11 | backtrace.io | Network issue

[yoann]

Hello,

I have a strange behavior with the latest version of Eucontrol: I can't launch the application.

It bounces in the dock and never opens.

I tried on different computers, with the same problem: Eucontrol 2023.11 does not launch (Eucontrol 2022.9 is OK)
But I noticed that the problem only occurs when I am connected to the specific network of the studio.

When I am outside, Eucontrol opens normally.

I need to use Eucon in this installation, and after many tests, I think the problem comes from the specific configuration of the Internet access.

We have an ISP that provides Internet access to a first router that I cannot access or configure.

This router automatically assigns (DHCP) an IP address to a second router, the router of the installation, which gives an IP address to all the computers we use.

I can access this second router and configure it.

After some more testing, I found out that Eucontrol is trying to reach www.backtrace.io.
When I block this domain in the host file on Mac OS, Eucontrol finally opens.

Is there another way in my setup to allow Eucontrol to work normally?
Is the connection to backtrace.io important?

Please note that we also have an S6 in the facility, which works fine.

Best,

Yoann
