Cannot access ESXi host web page from attached VMs

Running ESXi 5.5 build 3116895

I cannot browse to the ESXi ip address from any VM host

The http request just times out

I have server 2012 R2 and I just installed a Windows 7 VM - same result

All firewalls are off on the VMs

I can browse to ESXi from any other machine on the network - the http request redirects to https and I get the standard VMWare ESXi Welcome page

Any ideas as to what is blocking or re-routing http/https traffic internally on the ESXi host ?

Can you post details of your vSwitch configuration including the vmkernel port the ESXi host uses for management and the Port Group(s) your VMs are connected to?

This is small VM - just 4 Hosts

Security - Defaults -  Reject / Accept / Accept

Traffic Shaping - Status - Disabled

NIC Teaming

Load Balancing - Route based on the originating virtual port ID

I do not have VMKernel installed

I have 1 VM port group - VMs are connected to it.  There are 2 NICs teamed

Is there any VLAN tagging on either the vmkernel port or the VM port group?

What IP address / network mask is configured for the vmkernel port and on the VMs?

VM Kernel IP - 192.168.10.201 / 255.255.255.0  .... G/W is .10

VMs are 192.168.10.xxx / 255.255.255.0  ... G/W is . 10

VLAN is set to 0 - no tagging

Some other symptoms

When I SSH into the host and ping the other VMs, I get packet loss of 66% to 100%

I can ping from the VM to the host with no loss

What is you disconnect one of the nics or remove one of them from the vSwitch? Try removing one and of that doesn't get it working put it back and take the other one out. Perhaps there is an issue on your physical switch configuration. Are the ports on the physical switch configured as an Etherchannel or LACP team?

I disconnected each of the NICs one at a time from the vswitch - made no difference

I'm not on site so I'll have to get someone to physically disconnect each connection to the switch.  The switch is an older Cisco non managed 1 GB switch

Fixed ...

I gave the ESXi host a new IP and everything worked properly.

Further investigation showed that the BMC on the server had the same IP address
