Ok its been a week since I setup a 3 node cluster and this is the first day that this happens.
When I access the MCS it just show a loading screen @_@ .
The first place to look for will be in the /opt/mapr/logs/adminuiapp.log on the web server node to see if there are useful MCS events that might give an indication.
Is it the same from other browsers as well?
Once you have the logs, take a look at:
why can not access the MCS page

Also check out MCS not opening after setting up single node cluster, successfully. It may be helpful.
Make sure the webserver (mapr-webserver) is running on the node at that IP address.
was the issue resolved?. Please share your solution so other members may benefit.
Resolve but Idk how, it just work one day and im puzzled why.
This is a firewall issue. Please check with firewall team if there is firewall issue, ensure you have all required port open as mentioned in mapr 5.2 docs and change the port number set up the port number if your giving default change the port number and see that should work.
iptables and firewalld are all shutdown
