we have 4 ESXi Servers in our environment which hosts multiple VMs. These ESXi hosts are managed individually with VMware vSphere client (software). We do not use VCenter.
3 hosts are working fine, problem is with only 1 ESXi host which is not getting connected via vSphere client.
I am able to ping that IP but not able to take ssh session of that host. cannot open via web as well.
i am able to ping and take ssh sessions of virtual machines hosted on that ESXi server.
but cannot open it through Vsphere client.
Just a thought. Ensure that you don't have another system that has (accidentally) the same IP address assigned to it.
What you may try for troublshooting, is to run arp -a, and check the MAC address that shows up for that IP address after running a ping.
