TFS | TF400324: Team Foundation services are not available | The underlying connection was closed

 Recently I found this interesting issue on one of my AX2012 Dev machine which connects basically to TFS. 









Problem's keywords

  • TF400324: Team Foundation services are not available
  • The underlying connection was closed


Solution

I found that these following instruction works for my case.

1.      Open up a PowerShell command prompt, running it with elevated privileges

2.      Run the following command for 64 bit applications:

# set strong cryptography on 64 bit .Net Framework (version 4 and above)
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord 

3.      Run this command for 32 bit applications

# set strong cryptography on 32 bit .Net Framework (version 4 and above)
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord 

4.      Reboot.
