Now, we've added error page management to the GeoBIM Portal, so instead of an ugly page, you get to a real error page where you can choose to go back to the homepage.
We have also expanded the session times so that you do not get thrown out so fast anymore. The time is set to one hour, please return to us if you feel this is incorrect. Now it will also work to end up on the login page when the session has expired, instead of getting a server error message.
