call to selenoid container (post ../session) for creating a new session
error was returned after 30 seconds
selenoid's default timeout for session creation:

-session-attempt-timeout duration
    New session attempt timeout in time.Duration format (default 30s)

Selenoid would have returned New session attempts retry count exceeded but request doesn't make it to get to the selenoid process stage.
Possible reason: selenoid's container firewall blocking this incoming request
