OnVUE-22.16.54.
All checks before "Launch simulation" step are OK.
But after clicking "Launch simulation" button on "System test - Exam simulation - Launch simulation!" page, new application window appeared, what "lock" the screen, with progress bars downloading content but eventually "Message from webpage" pop-up warning window with "Communications error has occurred. ..." message is appeared. After closing this pop-up window i got "Congratulations you’ve completed an anonymous system test". But according to guidence it should be simulated question.
I tried two different laptops, following all technical recommendations, both wireless and wired ethernet connections. Also tried three different internet providers to exclude local network issues. Closed application and shutdow processes. Played with firewall and anti-virus. Nothing helped.
Found nothing special in Windows System event logs.
So i wonder if laptop passed the verification or no? If no, then how to find out what causes this error?
