The release of Full Guys: Ultimate Knockout as a free game on all major platforms is causing some errors, including an 'Authentication Failure' message that pops up, but there are a few different fixes that can be tried to potentially fix the issue. New and returning players are coming across the 'Authentication Failure' error as they attempt to load the game or find a match.
