ARL Import Failed with

[fawad_laiq]

Hi Champs,

After FNMS Upgrade to 2023 R2, I am facing ARL update failure. I can see below error in logs:

[.RecognitionImportTool] [ERROR] Unexpected error occured 2024-05-24 14:21:14,370 [.RecognitionImportTool] [ERROR] ManageSoft.Compliance.Security.Cryptography.CryptographyException: Cipher text "fqngZ3WkGtcR5PJdAdBbBw==" cannot be decyphered ---> System.Security.Cryptography.CryptographicException: Bad Data. at System.Security.Cryptography.CryptographicException.ThrowCryptographicException(Int32 hr) at System.Security.Cryptography.Utils._DecryptData(SafeKeyHandle hKey, Byte[] data, Int32 ib, Int32 cb, Byte[]& outputBuffer, Int32 outputOffset, PaddingMode PaddingMode, Boolean fDone) at System.Security.Cryptography.CryptoAPITransform.TransformFinalBlock(Byte[] inputBuffer, Int32 inputOffset, Int32 inputCount)

Need your input to get this solved.

Does your application server connect to the Internet through a proxy to download ARL content?

There was a change at some point to use a more secure cryptographic algorithm for encrypting sensitive proxy data that may invalidate previous proxy configuration when an upgrade is done. That can lead to the following error you have noted:

ManageSoft.Compliance.Security.Cryptography.CryptographyException: Cipher text "...==" cannot be decyphered ---> System.Security.Cryptography.CryptographicException: Bad Data

If you are using a proxy, please reconfigure it using a command line like the following:

"c:\Program Files (x86)\Flexera Software\FlexNet Manager Platform\DotNet\bin\MgsImportRecognition.exe" -ps <ProxyServer>:<ProxyPort> -pu <ProxyUsername> -pp <ProxyPassword>

For reference, the following article contains some more details about configuring the system to use a proxy for downloading ARL content: Configure ARL import to use proxy server without using Internet Explorer settings.
