I was trying to complete a module in Trailhead when I recieved this error.  I did also create a new org and I am still recieving the same error. 

There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: UUAIAOQQ
