-------- Weitergeleitete Nachricht -------- Betreff: Windows 10 & CAT - TLS Session reuse error Datum: Mon, 20 Dec 2021 11:57:58 +0000 Von: Darren Wheatcroft <Darren.Wheatcroft AT nottingham.ac.uk> An: cat-users-request AT lists.geant.org <cat-users-request AT lists.geant.org>

Hi,

        We have recently updated our certificates and the CAT tool has
        been updated accordingly with the cert chain.
        
      
      
        
      
      
        Since doing this, no Windows 10 device will connect to eduroam -
        we get 'Unable to connect to this network' on the client, and
        'TLS Session Reuse' on the Clearpass server.
      
        
      
      
        MacOS, iOS and Android all connect OK. It isn't our build of
        Windows 10 as it happens on personal machines as well.
      
        
      
      
        Essentially the only thing that changed in the CAT tool this
        year was the certificate chain.
      
        
      
      
        Manually forgetting, then connecting will work every time.
      
         
      
      
        Does anyone know of any client side logs we could dig into to
        see what is going on? This years cert update has been a bit
        challenging!

          Kind regards
        
          
        
        
          Darren
