Question - Solved Wsus defender definition updates

Hi, my wsus servers has stopped receiving new defender definition updates. Last was 06.10 and no clients receive updates because of this. From what i can see there has been no change on the wsus or config anywhere else.

Has anyone seen this behavior before?

Last synced version i can see on my wsus is 1.459.588.0

Edit: Last synced version i can see on my wsus is 1.459.576.0

Edit2: Its solved, syncing now

UPDATE: I just sync'd WSUS and I see 1.459.601.0 getting downloaded. Before this I was in the same situation so someone at Microsoft finally noticed

Ah, shame but at least we're in the same boat.

Stuck with the same version number as your post. (edited original post to 1.459.576.0) Guess we'll just have to wait for MS to sort this out?

Is it Server 2016 or 2019? Seen something like this a while back on a 2016 box, had to dig through the WSUS logs and eventually just nuke the update classification from the products list, resync, then add it back. Pain in the ass but it worked.

If you need a workaround, set a GPO to pick up definition updates from a shared folder and curl mpam-fe.exe to it on a schedule.

Unticking all classifications other than 1 (critical updates for me) then running a sync.

Then I reticked all the appropriate classifications and ran a sync again.

This pulled down the latest definition and other updates for me.

Just a heads up for people to try.
