Hi @Avraha Zilberman, what machine did you choose for Sandbox offering on Azure A4? Also, I would like to suggest if you can edit your previous posting of the error and just have a small snippet of the error stack and put the full log in a file. It will prevent having to scroll down to get to the next post.

@Avraha Zilberman you need to make sure your endpoints are open for hbase and all other products. Please look at our documentation for port information. The doc is for Windows but should be applicable for ports on Linux as well. Is your firewall up?

@Avraha Zilberman before doing anything involved, try to create a new machine and use it. If there are no issues there, you can safely remove it. If you continue to have the same problem, you will have to look at Azure documentation. We actually have good step-by-step guides here for using Sandbox on Azure.

Thanks ,

I have already created new machine and I get the same effect.

Can you please put a link to the azure documentation I will need it because on the next following weeks I will put my app on beta.
