I am upgrading from 12 to 19 (yes a big leap). I can't get BIM server to work. I have tried to install it on our server running windows server 2011 and when that wasn't working, a windows 7 workstation. I was on the phone with Graphisoft support and he verified all my settings looked good. Whenever I try to share a project I get a message box saying "Connection to the server ["Server name"] cannot be established. Try to reopen this Project when the server is online." When I test the connection in the sharing dialog box, it says "bim server is accessible". I get the same message for both BIM servers. Help!
