I have installed Alfresco on a windows server. It works well within the LAN. When I access outside of LAN network I get following error after login. (Please see attachment)
Note: I am able to get to the login screen.
Something's wrong with this page...
We may have hit an error or something might have been removed or deleted, so check that the URL is correct.
Alternatively you might not have permission to view the page (it could be on a private site) or there could have been an internal error. Try checking with your Alfresco administrator.
If you're trying to get to your home page and it's no longer available you should change it by clicking your name on the Alfresco toolbar.
