Can you help to resolve this issue?

Hi,

From the error message, it seems that the project is not avaliable.

Have you ever performed a migration before?

Best regards

I checked with my talend admin and it was found that , corrupted project setting caused this. see the below message from him.

There is a conflict in project setting in TAC,  that’s why we are not able to connect with project.

So the settings was reverted to the previous setting and the red icon in the above picture has turned Green.

After that admin has given the project settings file which we need to replace in the following workspace path

\<Your_workspace_Path>\<Your_ProjectName>\talend.project
