Hi,
Since the issue is occurring on your desktop which is connected via Ethernet but not on your laptop or cell phone which both connected via Wi-Fi, it suggests that the problem may be specific to either the desktop's network configuration or its hardware. Here are some steps and considerations to help diagnose and potentially resolve the issue:
Ensure that the drivers for the network adapter on your desktop are up-to-date. Outdated or corrupted drivers can cause connectivity issues. Visit the manufacturer’s website to download and install the latest driver version. Or you can open Device Manager, expand the Network adapters section, right-click on WAN Miniport (IKEv2) and select Update Driver
Within Device Manager, see if there are any warnings on the WAN Miniport adapter. Try uninstalling the adapter and then restart your computer so Windows can reinstall it.
Sometimes security software can interfere with certain types of connections. Temporarily disable your firewall or antivirus to see if this resolves the issue. Remember to re-enable these protections after testing.
As a last resort, you can reset your network settings to default. In Windows, go to "Settings" > "Network & Internet" > "Status" > "Network reset". This will remove all network adapters and set TCP/IP back to their original defaults.
Best Regards,
