vCenter 503 Service Unavailable

1. You have just updated vCenter (in my case, VCenter Appliance with PSC 6.0 to 6.0U2)

2. You have restarted vCenter, waited for ~ 10 minutes and trying to open web sphere client

3. Unfortunately,error appears:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x7fb16c058ad0]

_serverNamespace = / _isRedirect = false _pipeName =/var/run/vmware/vpxd-webserver-pipe)

OR Information message:

The vSphere Client web server is initializing

4. To fix it go to VAMI (https://<vcenter fqdn>:5480) and check overall health status.

vcenter appliance health status

5. To check services manually, enable SSH and BASH from html client

6. Or login to direct console (DCUI) and enable SSH/BASH from there

7. Open Putty and connect to vCenter Appliance, type root password and shell

8. Check status of services again

9. Check vSphere web client service status

service vsphere-client status

10. Try to restart or start service and check status after manipulations

To restart:

service vsphere-client restart

To stop and start manually:

service vsphere-client stop
service vsphere-client start

11. vSphere Web Service should be running and overall health indicator status is green or, at least, yellow

vcenter appliance health status 2

12. Try to open vSphere Web Client

Note:  you also need to make sure that there are no issues with DNS and IP allocations in your network (DNS is available, there are no IP duplicates, firewall deny rules and etc.)
