Operate api calls are not showing in Network tab

Hello,
I am using C8.1 self managed Helm chart and running smoothly and yesterday we had increased the disk space for ES due to shortage of space. All the nodes are running/healthy.

Now, I am unable to see any operate API call in network tab of browser, though instances and the status of the process can be seen in operate dashboard without process variables.

Could you please assist me on this about the RCA?

TIA.

Hi @yadav1990 - do you see any errors in the console tab?
