Over 600 Domain computers won't get windows updates

[MOoD90s 0]

I desperately need help! We have 3200+/- total domain computers all on windows 11, mostly Enterprise and some on Pro, 600+ of them haven't done updates since either November of 2024 or August of 2023. They get an error when trying to do updates that says, "We couldn't connect to the update service". I have tried many things, verified all the Registry setting were correct, update troubleshooter fails, I can ping the update serves successfully from a CMD prompt, restarted services, deleted software distribution and other folders, I can manually push updates, but it won't auto pull them. Any help would be greatly appreciated.
