Selenium Grid question.

[Madis Kangro]

Hello. So here im having some troubles and questions. 

When i start a hub should the hub status be from the get go. As soon as i start it it is like that. When i add a node to the grid nothing changes in the hub status. The node appears in the http://localhost:4444/grid/console#

Hello

Am seeing the same issue. Were you able to debug this? It would be really helpful if you could pass on your findings.

Thanks!

Niranjani,

Can you please help add a bit more context to the problem ? What all are you doing before you encounter this problem. Mere stacktrace doesnt help too much in terms of finding out what went wrong.

Thanks & Regards
