I have a Server with Project Server 2016 running and a Client with Project Professional and the newest IE.
After I setup the Server everything was fine, I could access and edit projects from Professional and from the browser. But after a week cant edit a project via the pwa, but I can see it.
Thats the error message:
An error occurred while opening your project. Give us a few minutes and try again. If this happens again, contact your administrator.
Info: I have all needed permissions. Even the site-admin cant edit it.
since the i configured the server, I did several changes including custom fields.
After the error happens, the project is checked out.
If it is not clear, ask me for more information.
