ESXi Lockdown Mode grey'ed out

Hi,

I'm struggling to add a host back in to vCenter 6.5 appliance

ESXi 6.5, build 16207673

when i try to web client to the host i get the message

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x0103f858] _serverNamespace = / action = Allow _port = 8309)

i can ssh to the host using the root account

i can DCUI to the host via root account

when i DCUI to ESXi host the lockdown mode is enabled, i'm not sure if its strict or normal.

is there a SSH command i can run to disable lockdown mode. is it Lockdown mode thats causing the above error?

I cant add the host to vCenter either as i know within the web client you are able to disable lockdown mode

is the Lockdown mode greyed out because the root account doesnt have the permissions to change that? the root account is the highest account for this host, its not on the domain

Hello,

No, lockdown mode does not cause "503 service unavailable error." It seems an error about management plane.

Please make sure hostd service is running:

/etc/init.d/hostd status

Restart:

/etc/init.d/hostd restart
