I have succeeded again in logging in via my phone Chrome browser, and find that I am running ESXi v6.5 build 2, not v5 as I thought earlier.
But I still can't log in from my computer. Why not?
And is there a way to edit my original post? I can't see it, if so.
You could try using powercli to log into the host .....
# vCenter Connection details
$vCenterFQDN=”hostname or IP address”
Write-Host “Connecting to vCenter” -foregroundcolor “red”
Connect-VIServer -Server $vCenterFQDN -User $vCenterUser
Thank you. Unfortunately, I don't fully understand your answer.
What is 'powercli'? I guess that the cli refers to 'the command line', but don't understand the rest. Is it something I should be able to access from my computer, even though the browser access doesn't work any more?
Do I use an SSH connection and terminal to access the host manager of ESXi and type in the commands in the last two lines?
I've tried doing that from my iMac, using vSSH Lite, and the username root, with the password that works from my phone.
It won't connect by SSH, just hanging with a black screen, eventually saying 'operation timed out', followed by disconnection.
I still don't understand:
a. Why browser access has suddenly stopped working - on Chrome, the connection is just refused. Using Safari, I can get as far a login screen, but the password isn't accepted.
b. Given that, why I CAN still connect using a browser on my phone.
At least when I use Safari now on the iMac, connecting to the host IP address, it gives me a login screen, not just an error message. But it then rejects the username/password combination I used successfully on my phone (root user, previously working pw), by blanking out the password field and re-displaying the login screen.
And before this distraction, I'd actually like to start replacing the single existing 1GB hard drive, which is getting full, with a bigger 4GB one, and an SSD 120GB system disk.
Should I just start over with the new hardware, and rebuild the system from scratch?
i've also posted on the CentOS 7 forum about the second issue - how to replace the disks.
But if I can't properly manage the host, that seems a risky thing to try, short of starting again.
