Description
Error: "SSL Error 61: You have not chosen to trust 'Certificate Authority'..." When Launching Apps with Citrix Online Plug-in
Users may be unable to launch apps with the Citrix Online Plug-in.
The following error message appears:
"Unable to launch your application. Contact your Helpdesk with the following information: Cannot connect to the Citrix XenApp server. SSL error 61: You have not chosen to trust <name of SSL Certificate Authority>, the issuer of the server's security certificate."
Resolution
As of this writing, the following older Citrix products have been validated to support SHA-2 certificates:
- Secure Gateway 3.3.4
- XenApp 6.5 with Hotfix XA650R06W2K8R2X64023
- Web interface 5.4.2.59 with the below mentioned configurations for different XML transport types.
- Citrix Receiver 4.1, or later.
It is recommended to use StoreFront and a current version of Citrix Receiver, rather than Web Interface and Citrix Online Plug-In both of which support the higher SHA-2 certificates.
Problem Cause
The older Citrix Online Plug-in does not support SHA256 signature algorithm.
