Cient Connexion not working on SmartBear

Hi team,

We are currently facing a problem with one of our user.

The application is installed on a VDI, on Vmware horizon.

It's imposible for her to connect to the application ( using the shortcut 'TestComplete' ),  but her coworker are able to connect.
When she try, she get this error  " Failed to open the https:login.slm.manage.smartbear.com/auth/app  Error message: ERR_CONNECTION_REFUSED  Error code: -102 "

But in the smartbear console, all seems good.  I'm even able to see other connection :

Could someone help us ?  thank a lot by advance
