The modeler only allows me to create project locally and if I upload the project to the team server it is giving error, and also unable to download the project into modeler which was created from the mendix developer portal. In modeler, Run in sandbox option is also disabled. Please provide the cause and solution. Thanks in advance, Sudarsan
It seems like your modeler is having trouble connecting to the Mendix servers. Perhaps you recently changed your password? Relogging/restarting your modeler seems like safe bet. If that doesn't work, you can try a fresh checkout of your project. If that helps you can then transplant your changes from the 'broken' project to the new one.
