After disconnected no longer iscsi device then suddenly occurred error in storage menu on Cockpit Navigator. Said “cannot open /etc/cockpit/disallowed-users”.So, I did following steps.
Edit to add user in /etc/cockpit/disallowed-users.
Restarted cockpit service.
Also, cleared browser cash.
Still shows storage error.
Menu of others are worked fine.
Do I need to reinstall cockpit?
No, you need to fix the config.
What is the error you are seeing after your fix?
Here is Error logs.

Suggest that you raise a bug against this problem with the details in your reply.

Created Redhat account.
Difficult to raise report. How do I create.
I thought the docs I linked to explained?

Hello @tamoto ,
Welcome to 
!
This is cockpit you are talking about? You had an external storage device that is no longer plugged in? Perhaps your /etc/fstab needs a line commented out for the external mount point.
External outdated mount point on /etc/fstab was commented out before.
Are there any services to be restarted.
Finally, reboot fed 39 and recovered storage function of cockpit.
