Hi!
I have a problem with getting results from my private instance of WPT running on Ubuntu 18.04 (in VirtualBox, Windows 10 is host).
After ending the test I got no results but the message “The test completed but there were no successful results.”. I’m using nginx server. I would be very greatful to you if you would give me any hint how to solve this issue.
