We are using Alfresco Community - 5.1.0 (r127059-b7).
Sometimes users are not able to see the login window, if using VPN connection.
They can only see "Simple+Smart" in the right bottom corner.
Thanks for help.
Could you check logs of the server, please?. Maybe you can find more detailed information.
Could it be in relation with CSRF (Cross-Site Request Forgery)?.
Could find any log entry.
I never touched CSRF, shouldn't be the problem.
Please check the browser console / browser tools if any errors pop up, or the browser network tools to see if any resources failed to load. A (semi-)blank page is a typical sign that some part of the UI simply did not initialise, either due to missing artifacts or some other component preventing proper execution.
