Citrix Web Interface 5.3: An error occurred while making the requested connection
March 29th, 2010
I tried to configure a Citrix Web Interface 5.3 server in conjunction with Citrix Presentation Server / XenApp 4.0 and a NetScaler. It is possible to login, but I cannot launch an application. When trying to launch an application I receive the following error message:
An error occurred while making the requested connection
I found an related article on the Citrix website. This article applies to Web Interface 5.2, but also works for Web Interface 5.3 The symptoms in the EventViewer for Web Interface 5.3 are different, but gives me more specifications about the problem. In the event log of the Web Interface 5.3 server you will receive the following error message.
After changing the RequireLaunchReference parameter in \inetpub\wwwroot\Citrix\XenApp\Conf\WebInterface.conf applications can be launched without any problems.
Add On: if the above solution doesn’t work, then a second solution for this problem can be found here
