Cloud key not responding... weird

Hey, maybe anybody around here seen that before.

I have a Site running Unifi Switches and a Cloud Key G2, unfortunately since days the CK is not responsive. I can ping it but I can’t access the WebIF nor SSH. Remote (Cloud) Management is also not able to connect.

SW201 is the switch the CK is directly connected to 0/2 from Switch SSH:

SW201Server-US.5.43.23# ssh -A admin@
ssh: Connection to admin@ exited: Connect failed: Connection refused

SW201Server-US.5.43.23# curl
curl: (7) Failed to connect to port 8443: Connection refused
SW201Server-US.5.43.23# curl -v

Connection sto :8080 are possible “HTTP Status 400 – Bad Request” but 22 and 8443 both immediatly get “connection refused”

Rebooting does not help.

The CK is connected to a USW-16-POE which is connected to a US-16-XG.

The Management VLAN is the native PVID on the network, even from the Switch SSH where the CK is connected to I cannot connect to it via SSH nor 8443.

Any Ideas?


Just a small update:

Seems Unifi have some issues currently, I’m not the only one:
