I was using SAP Web IDE FullStack on NEO Europe Trial region yesterday and suddenly I was not able to preview my UI5 apps when running then using any run configuration.
Still now the same issue is happening only in this NEO region and only in the FullStack Web IDE edition.
@sapcp Twitter profile suggested to create a question to document that issue.
I took some snapshots of what happens when I left click a project inside the workspace and also the result when running the app using Web IDE
