Browser pods are deleted right after start

[anusha90267]

Hi Team,

We are using Kubernetes 1.27 on our on-premises cluster. We have deployed the application 'Scaling Selenium Tests using Selenoid & Selenosis' on our Kubernetes cluster. In the Selenosis web UI, 'SSE and SELENOID' show as connected. However, when attempting to create sessions, the browser pods are created and then immediately deleted. On the UI sessions page, we see the AJAX error: 502. In the Selenosis pod logs, we encounter the following error:

`

_time="2020-12-21T10:28:20Z" level=error msg="session failed: Post \"http://selenoid-vnc-chrome-87-0-af3177a0-5052-45be-b4e4-9462146e4633.seleniferous:4445/wd/hub/session\": dial tcp: lookup selenoid-vnc-chrome-87-0-af3177a0-5052-45be-b4e4-9462146e4633.seleniferous on 10.96.0.10:53: no such host" request="POST /wd/hub/session" request_id=fa150040-86c1-4224-9e5c-21416b1d9f5c time_elapsed=5.73s_

`

We have followed the steps provided in the description to modify the CoreDNS pod configmap, but the issue persists. Please let us know if there are any other solutions or troubleshooting steps we should follow. We have been facing this issue for multiple days, and your inputs would be very helpful.

Thank you.
