Graphs not showing

I have taken reboot of of my kibana cluster, post reboot the graphs are not showing neither for 15mins or any orher timeline.Earlier it was showing exceptions of

[2] total shards, but this cluster currently has [3902]/[3000] maximum shards open;

but post deleteing the old indexes, that exceptions gone but still graphs not showing.

Pls help

Welcome to our community! :smiley:

What do your Kibana logs show?

Thanks....
