I have downloaded MarkLogic Server version 8. I have configured initial admin steps and I am able to open http://localhost:8001 and http://localhost:8002. However while opening http://localhost:8000 shows 404 error. This never happened before. Can anyone please help me finding what might be the possible reason?
It is likely that port 8000 is used by some other application on your system. You can either find and disable that application or change the port from 8000 to some other port (say 8100) from within the admin console.
