Small hint for those, receiving following Citrix XenApp 7.6 error while opening any app from Receiver – “Cannot start app, please contact your help desk“:
Additionally, in the event log you find repeating errors from Citrix Store Service, EventID 0, message:
The Citrix servers do not trust the server. This message was reported from the XML Service at address http://deliverycontroller.domain.local/scripts/wpnbr.dll [NFuseProtocol.TRequestAddress].
All you need to do, is set up TrustRequestsSentToTheXmlServicePort from $false value to $true. Simply follow these steps:
- Log on to your Delivery Controller and open powershell console
- Load Citrix snapins:
- ChangeTrustRequestsSentToTheXmlServicePort parameter value to $true:
PowerShell1Set-BrokerSite -TrustRequestsSentToTheXmlServicePort $true
- And finally you may want to check the result by typing:
PowerShell1Get-BrokerSite | fl TrustRequestsSentToTheXmlServicePort
If value is set to $true, issue should be resolved.
