Could be a network problem then.
Do you have a proxy in your environment
If you do are all the required URLs allowed, and have you setup defender to use said proxy?

Hi Jonhed, After we check with network team some of MDE update definition update url was blocked by firewall, now Microsoft security intelligence got update is working as normal. Just to verify about GPO that shared with you as attached picture there's correct or not?
Good to hear that you was able to fix the problem.
I do not see any problem with your GPOs.
Just to confirm, have you been able to update the antivirus platform version as well?
The platform version updates is usually done through the regular OS windows updates, so if you use WSUS or SCCM etc to manage normal OS updates, you will need to setup those resources to distribute platform updates.
If you just update the OS straight from the internet, and do not manage it internally, there should not be any problems.
