A new Horizon environment has gone into production.

A new Horizon environment has gone into production. External sessions are being disconnected after a random period of time.

The following information has been documented by the administrator:

. Internal and external users are able to connect to their desktops.

. External sessions connect via Unified Access Gateway.

. Users are immediately able to reconnect but are disconnected again in a few minutes.

. Due to limited amount of public IP addresses, all traffic flows through a load balancer.

. Internal sessions, connected directly to the desktops, are not impacted.

. While the session remains connected, all expected functionality works properly.

What could be a cause of this issue?
