[Defender] Connect to ManageWP

Hello,
I like to ManageWP backup feauter , Actually I am using it for few months ago , but when I start using WPMU Dev plugins .

Website disconnect from ManageWP , I connected them support they asked me to whitelist them IPs I did and I still have the error .

I see that with website with Defender , so I guess the conflict with it

How can I solve that ?

Thanks
