This article was created in response to a support issue logged with K2. The content may include typographical errors and may be revised at any time without notice. This article is not considered official documentation for K2 software and is provided "as is" with no warranties.

Issue

Azure has a default idle timeout of 4 minutes. This means that if you leave the P&D app unattended for more than 4 minutes and then continue to use it, connection errors will appear. Please see this link for more information.

Resolution

All K2 Cloud instances are pre-configured with the maximum timeout (30 Minutes). If the Remote P&D tool is used from an Azure hosted VM, the same config on the NLB applies.
