I may need more information to help you deal with this question: 1. Did this problem happen suddenly? 2. Is it local network or Azure net? 3. Did you add a domain? Is it a domain member? 3. What did you do when the problem occurred (updated system version or firewall, or added new group policy?).
Depending on your current situation, this could be due to a network policy setting that is enabled on your computer or due to the firewall defender.
We can start with some troubleshooting: 1. Turn off the firewall 2. Try disabling the network policy for the private endpoint 3. Check if there are any Azure Policy guest configurations that might affect your network settings.
Hope the information is helpful.
