My situation is 6.5 upgrade to 6.7u3

Symptoms

Accessing the vSphere Client (HTML5) of vCenter server in browser is failed with error message:

503 Service Unavailable (Failed to connect to endpoint: [class Vmacore::Http::LocalServiceSpec:0x0000025c4df77820] _serverNamespace = /ui action = Allow _port = 5091)

Services status in vCenter server with command "service-control --status --all" shows the "vsphere-ui" service in STOPPED status.

It is working in PLEX client ?

[w617450941]

No

[FlyinRhino67]

Have you checked the VAMI? (port 5480)

Is the Upgrade completed?

[w617450941]

[w617450941]

[Cedric RENAULD]

The VAMi interface start without anyjonction with the Apache service from vcenter

Hi @w617450941,

Could you please provide the vsphere_client_virgo.log from C:\ProgramData\VMware\vCenterServer\logs\vsphere-ui\logs and also vMon.log from C:\ProgramData\VMware\vCenterServer\logs\vmon.

Also 5480 will not work on Windows as this is the Management page for Appliance based server.

Regards,

Nirmal Nair
