Why Am I not able to see stdout, stderr for spark driver

I was trying to run my first sample spark application today in bigdata-labs.
I was checking for driver logs, which generally can be seen in stdout or stderr at driver end. But was not able to find them in the below link

Also, stdout and stderr present at the executors are not accessible. The link’s are not accessible.
Please shed some insight, if I am missing anything.
