Reason: Error reading from remote server

Any idea … pls

If you can ssh into the appliance try the following:

cd /var/www/miq/vmdb
bin/rails c
> SettingsChange.all

At this point you will see a list of all of the changes you made to the advanced settings. Find the ones you want to “undo” and one-by-one get the id number and do the following

SettingsChange.find_by(:id => <id>).destroy

replacing the <id> with the actual id number
