Hi Ura,
Hope you are doing good.
I think I know what the issue is. Are you using SSO encryption? If not, could you please set the parameter snc/data_protection/min to 1 and see if the issue persists? Check SAP Notes 150380 and 352295 for implementation of SSO using Kerberos in Microsoft Windows OS.
