Hi DAVO,
A few things you could try:
Make sure the Beelink GT-King Pro and the device you’re trying to connect from are on the same local network/subnet.
Check that network discovery and file/network sharing are enabled on the Beelink Official Website
If you’re using Wi-Fi, check that your router doesn’t have AP/client isolation enabled, as this can prevent devices from seeing each other.
Try accessing the Beelink directly using its local IP address instead of relying on network discovery.
Check the firewall settings on the Beelink and make sure they aren’t blocking local network discovery or the service you’re trying to access.
Restart both the Beelink and router after making any network changes.
