   Sorry for the late response, I was on vacation last week so 
emails/notifications got backlogged.  For this issue, @ronazhan can you share 
your thoughts?
   
   I am not entirely sure what is the best way to debug this. The error shown 
up there:
   
   ```
   Unexpected error:
         <*url.Error | 0xc0004c0210>: {
             Op: "Get",
             URL: "http://localhost:9080/ws/v1/apps";,
             Err: {s: "EOF"},
         }
         Get "http://localhost:9080/ws/v1/apps": EOF
     occurred
   ```
   
   that seems like the REST endpoint could not be accessed. Maybe this is 
because the scheduler pod gets restarted and we need to redo the 
port-forwarding? Here is how it was done during the initial setup:
