You can debug the process by visiting http://localhost:8088/cluster/scheduler. If everything is configured correctly you will see Active Nodes count different than zero.

My issue was tied with a simple lack of disk space.

I am not able to see anything in local http://localhost:8088/cluster/scheduler. this link you mentioned. Its says "The connection was reset". Is there nay possible way?
