503 Error when running ionic app




I have been working on an ionic application and it has all been going great! Works well, I can deploy it devices and so on. However, The last 2/3 days when I try to serve the application localy on the server and then open to view, it says “No Application Seems to be running here!” with 503 error. However, the commands I have ran are the same as the ones I always run and it has stopped working. I tested in on a different workspace and all seems fine so not sure what has happened. I restarted the server and killed all processes, but does not help.

Please let me know what could be causing the issue.

Kind Regards,
