Unable to login after vCenter was updated

  • Read

These days we patched the vCenter nodes to 41000 and one of them failed to login after the update.

The update process was finished successfully while after the reboot when I tried to login it through the VMware Appliance Management page I always got 'Unable to login' prompt and nothing happened.

I waited for several minutes and even I could login the updated vCenter to manage ESXi hosts and VMs, I still could not login the management page on port 5480. I made sure the password was correct so I guessed something was wrong after the update.

Google is always a great helper and I found below web page:

Solved: Unable to log into vCenter 6.7 VMware Appliance Management page

I got the same error in the log /opt/vmware/var/log/lighttpd/error.log:

With command 'service-control --status' I found the service applmgmt was stopped so I started it then I could login the management page.

It was weird that this service was configured to start automatically so I will update this post when I find the the reason why it was not started as expected.
