Unable to access MCS  | loading spinning wheel

Hi,

 

My MCS is acting inconsistently, while sometimes I am able to login, other times, it fails to complete and stays "loading" and fails to load the page.

 

We were able to identify a pattern:

When I open a new window and point it to local:8443 it shows the auth form within seconds, lets me fill user and passwd and submit. However that tab never finishes loading "loading". Nevertheless, any new tab I open on that same window will automatically let me pass to the MCS, no auth process.

 

So there seems to be something wrong with the login process.

 

Here is what the logs say when I open the first window:

(no more activity is shown)

 

 

Here is what it looks like when I opened a second tab:

So it seems like the first time the login process fails to complete and this information is never passed:

2016-07-13 21:40:44,960 INFO  com.mapr.adminuiapp.commands.ConfigCallable [pool-1-thread-103]: ConfigCallable: Parameters = [config, load]

 

Environment: mapr 5.1.0 upgraded from mapr 5.0 in centOS 7.2

 

Any help would be appreciated.
