Installation Failed error code 0x80070643 - WinServer 2016

[aneng]

DC is talking directly to atp portal and sensor, we already allowed this in our firewall.

We have disabled the proxy settings, its working on our first 5 DCs but failing in a couple of more DCs with same specs and are residing on same network object in the firewall.

Any recent solution what else can be check here please, appreciate any advise.

The error code alone is not specific enough without the details in the deployment logs.
Contacting support and sharing those logs in a secure file transfer workspace might result with a quick answer.
