Any ideas?

@gw3437 : the error indicates that the "server" part of the assessment tool did not start timely. The server part is an ASP.NET web server (kestrel) running on port 25010. If for some reason there's something else is already using that port then the server can't start. Can you check the following:

• Verify all microsoft365-assessment.exe processes are gone and try again (this can rule a rogue assessment process that somehow blocks things)
• If that does not work please try using a different port, see https://pnp.github.io/pnpassessment/using-the-assessment-tool/configuration.html#using-a-different-port-than-25010 for how to do that
• If that does not work, can you see if you can put the microsoft365-assessment.exe in a folder that's excluded from your AV scanning...trying to rule out it's impacting things
• Trying on another machine might help as well? What OS are you using to run the tool?
