Connectivity requirements

Session Recording cloud client

The Session Recording cloud client requires access to the following addresses:


Usage Port
For video playback Open port 9191 on end users’ devices and networks
For communication with the cloud Allow outbound ports 8088 and 9090–9094 on each Session Recording server


You can set up a proxy when installing the Session Recording cloud client. For more information, see Connect Session Recording servers.

Increase the transport packet size

  1. Locate the Web configuration file under <Session Recording installation path>/WebSocketServer.
  2. Open the Web configuration file.
  3. Edit the BlockSizeMultiple value.

    The default value is 1 (4 KB). We recommend you set the value to 8 (32 KB).

    The BlockSizeMultiple value

Install certificates in IIS

Add an SSL binding in IIS so that:

  • The Session Recording servers can connect to Citrix Cloud properly.
  • You can use HTTPS to access the player.

For more information, see step 1 of HTTPS configuration.

Switch to web streaming service version 2.0

A fresh installation of Session Recording 2103 and later connects your web browser to the web streaming service hosted in IIS when you access the player. The web streaming service hosted in IIS is versioned 2.0, as indicated by WebSocketServerVersion under HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\SmartAuditor\Server.

Web streaming service version

An upgrade installation from an earlier version to Session Recording 2103 and later connects your web browser to the Python‑based web streaming service, which is versioned 1.0. To connect to the web streaming service hosted in IIS, run the <Session Recording Server installation path>\Bin\SsRecUtils.exe ‑enablestreamingservice command.
