Selenium/Fitnesse loses session during test ( - selenium

Question

I'm using Fitnesse to create tests. When I run them in de webbased tool they succeed. When run via Microsoft Visual Studio Team Foundation Server I get the following error, although sometimes it seems to run normal at the same point but in a different testcase.
org.openqa.selenium.WebDriverException: Unable to execute request for an existing session: Unable to find session with ID: <session-id>

I have already tried updating the edgedriver and extending the grid session-timeout but it doesn't seem to help.
