Nvidia SDK Manager Windows 11 Login Issue Timeout

Good afternoon,

I recently acquired a new Nvidia Jetson Thor system and so I just setup my Nvidia account to install the Nvidia SDK Manager.

I can login to the website and forums without issue, but when I try to login to the Nvidia SDK Manager program on my Windows 11 computer, the SDK manager has an issue and says that the “Login token could not be validated”.

I made sure to set my proxy settings correctly, it does the handoff to the “Login credentials retrieved successfully” message but then fails to the “Login token could not be validated” message. I set the log verbosity to Debug and exported the logs, but I see that there is an error once it has the credentials: [error: JWT decoded failed with error: Error: connect ETIMEDOUT 52.206.180.49:443].

I’ve attached the log file. Thanks in advance!

Hi,

Please check if there’s a VPN or firewall running in your environment. If so, try disabling it and run the sdk manager again.

Thanks

It’s definitely something in our corporate proxy/firewall stack. I’m working with my IT group to figure out where in our proxy the request is being rejected.

Here’s a potential way around proxy / method to use a qr code to authenticate for nvsdkmanager.exe

You could try following to see if it helps.

# In powershell or cmd/Command Prompt

copy "C:\Program Files\NVIDIA Corporation\SDK Manager\responsefiles\Windows\sdkm_responsefile_sample_jetson.ini" $HOME

# Edit it and add your values.

notepad sdkm_responsefile_sample_jetson.ini

# To download jetpack 7.1 run 
NvSDKManager.exe --cli

# Then install Jetpack with 
NvSDKManager.exe --cli --response-file  ./sdkm_responsefile_sample_jetson.ini 

# Or this
NvSDKManager.exe --cli --action install --login-type devzone --product Jetson --version 7.1 --target-os Linux --host --target JETSON_AGX_THOR_DEVKIT --flash
