SCCM 1702 WSUS Not syncing

[mc111]

Hi,

OS: Server 2012 R2

SCCM: 1702 (and the hotfix)

This has been happening for a while now, and I have tried many, many option to no avail.
WSUS stopped syncing with Microsoft. Did all the usual checks, ports, hotfixes, etc. I have tried removing WSUS and SUP, rebooting and re adding it, still not working, but a different errors. It did start syncing at one stage, but failed. I have attached the logs. 

Please help!!!

Had something similar recently. Fixed by:

1. Deselect all update classifications in SCCM - run a synch and it will say nothing to sync

2. On WSUS server run wsusutil reset

3. Re-Select the classifications in SCCM and run a synch
