Sometimes, the WebUI services will not run if the VIP or eth0:0 is not populating for Junos space. This article explains how to identify the cause

To identify the issue, please check if the customer has made any changes to any directory structure. For example, moving all the files from /var/log to another directory.

If they have moved all the files from the "/var/log" directory" and rebooted, this issue will occur as shown in the below example

cd /var/

mkdir dir1

ls -l

mv log/* dir1/

As per the above output, the customer moved all files from /var/log to the directory dir1 after installation which created the problem after reboot.

We shouldn't move any files from the /var directory. But you can copy it.

To Fix the issue, please revert the changes

or

Please re-install the Junos space again and it is not suggested to make any changes to the system after installation.
