If you cannot access the vCenter Server Managed Object Browser (MOB) at https://vCenterFQDN/mob/ and your browser shows this error:
503 Service Unavailable
but all other services are up and running, this mean it has been disabled.
The issue occurs if the <enableDebugBrowse> parameter in the vpxd.cfg config file is set to false
Here is a runlist to resolve this issue:
- SSH to your vCenter
- In vCenter Server, open the vpxd.cfg config file using a text editor.
NOTE: the location of vpxd.cfg should be: /etc/vmware-vpx/vpxd.cfg
3. Locate the <enableDebugBrowse> entry within the file
4. Either remove the entry or change the value from false to true
#vi /etc/vmware-vpx/vpxd.cfg
<vpxd>
...
...
<enableDebugBrowse>false</enableDebugBrowse>
...
...
</vpxd>
5. Restart the vCenter Server services for the changes to take effect
#service-control --stop vmware-vpxd
#service-control --start vmware-vpxd
NOTE! In version 6.X service may be called simply vpxd not vmware-vpxd. To check it list all services running in your environment by typing this command: service-control –-list
