    Can't log in after changing IP on vCenter Server

    Wertyx Lurker

      Hello!

       

      I have a cluster based on VMware vSphere 5.5. I have vCenter Server running on a Windows Server 2012 VM.

       

      The issue: I need to change ip-address of my vCenter server and change vlan assigned to it.

      The VM has one virtual NIC with ip 10.20.49.10, for example. I created one more NIC when was changing IP on ESXi hosts (the new one is 10.20.43.10). With ESXi everything is fine, they correctly reconnected to Vcenter but when I change IP on vCenter I cannot log in to it using vSphere Client(message: Cannot complete login due to incorrect login or password).

       

      It happens when I disable interface with IP 10.20.49.10. When I connect using vSphere Web Client and try to log in I see message: " https://10.20.49.10:7444/sts/STSService/vsphere.local. The server might have failed to respond or responded in an unexpected way".

      When this interface is up I can connect to vCenter using both IP-addresses, everything is fine. Also if I disconnect NIC with ip 10.20.49.10 from the VM and reboot Vcenter services "VMware VirtualCenter Server" and "VMware VirtualCenter Management Webservices" fail to start. If I reconnect the NIC with 10.20.49.10, the services start again and I can connect both IP: 10.20.49.10 and 10.20.43.10 and log in.

       

      Does anybody have an idea what's wrong? How can I fix the problem ?

       

      Thank you in advance!
