There are no logs pertaining to iw-preview.war or it was down.
Thanks for the explanation. So is this user account specific issue?, because some of the users with the same access rights didn't experience this error message. They can view the updated component I did. We even tried simultaneously and I get the same error. Any other workarounds?
