This is due to some recent changes in Chrome regarding throttling JavaScript timer wake-ups. This has been forcing WebSocket connection termination in 5-7 minutes of tab inactivity.


1) Switch to a different web browser.

2) The throttling feature in Chrome can be disabled in Chrome versions below v90. Please use the following steps to disable this feature:
a. Type chrome://flags
b. Search for Throttle Javascript Timers flag, change it to Disabled.
c. Relaunch all the Chrome windows.
