Unable to execute request for an existing session: java.util.concurrent.TimeoutException for selenium tests triggered from Jenkins on GKE cluster


Chrome: node-chrome:123.0.6312.86-chromedriver-123.0.6312.86-grid-4.19.1-20240402 selenium/hub:4.19.1-20240402 dotnet 6

We have our selenium grid/tests run on parallel nodes on GKE cluster. Since sunday we are seeing the following exception

Unable to execute request for an existing session: java.util.concurrent.TimeoutException

and the tests are failing intermittently. We are also getting exceptions while capturing screenshots for most of the tests. While we are seeing the following screenshots for some tests, where some random html elements load instead of the actual application. This is blocking our regression cycle and we are out of ideas. Any pointers/help is much appreciated
