WSUS client win2016 not reporting

Hello ,

I am looking help on WSUS issue ,Where my WSUS client (windows server 2016 ) not able to report on my WSUS server running Windows 2012 R2  (WSUS 6.3.9600.18228).
On WSUS client name showing windows 10 and status showing NOT reported.

I have performed some basic troubleshooting as mentioned below but it didn't help me.

1. Stop the Automatic Updates service and BITS service.                        
net stop wuauserv                        
net stop bits                        
2. Delete “%windir%\softwaredistribution” directory.                        
3. Start the Automatic Updates service and BITS service. When these two services                         
have been started, they will auto-create “softwaredistribution” and its subfolder                         
at system directory.                        
net start wuauserv                        
net start bits                        
4. Stop the Cryptographic Services                        
5. Rename the C:\windows\System32\catroot2 folder                        
6. After the “%windir%\softwaredistribution” directory has been generated, please                         
let the client contact the WSUS server immediately.

Thanks
