The issue occurs when the WebAssembly (.wasm) files are blocked in your network. To resolve, verify the .wasm file MIME type is application/wasm, and is allowed in the network.

Supportability matrix

Citrix Workspace app for HTML5 supports access to desktops and applications through the following versions of StoreFront. Stores must be accessed through the Citrix Receiver for Web site. Citrix recommends the following:

  • StoreFront 2.5 (or later)
  • Citrix Workspace app for HTML5 allows you to upgrade from any version of StoreFront 2.5 or later.

When users connect through Citrix Gateway, Citrix Workspace app can be used to access desktops and applications that are delivered through:

  • all the versions of Citrix Virtual Apps and Desktops and Citrix DaaS (formerly Citrix Virtual Apps and Desktops service)
  • StoreFront that supports desktops and applications.

For direct connections through StoreFront without Citrix Gateway, Citrix Workspace app can be used to access desktops and applications through the following product versions:

  • XenDesktop 7.6 and later


Admins need to install Citrix Workspace app for HTML5 on the StoreFront server to make it accessible for the end users. Therefore, the build is in the form of the Windows binary. However, HTML5 doesn’t require any installation on the client side.


In a production environment, Citrix recommends:

  • securing communications between Citrix Receiver for Web site and users’ devices with Citrix Gateway and HTTPS. Also, you must have an SSL-enabled VDA.

    For more information, see the Knowledge Center article SSL configuration on VDA

  • using SSL certificates with a key size of at least 1024 bits throughout the environment where, Citrix Workspace app for HTML5 is deployed.

Citrix Workspace app enables users to access to desktops and applications from public networks with the following versions of Citrix Gateway.

  • NetScaler Gateway 10.5 and later

Citrix Workspace app for HTML5 now supports CloudBridge disabling compression and printer compression and using HDX Insight analytics to display in the CloudBridge Insight Center.

  • CloudBridge 7.4 and later


If there’s an issue to connect the SSL-enabled VDA with Citrix Workspace app for HTML5, configure the cipher suites as specified in TLS settings on VDAs.
