Having this error when launching an App-V/Softgrid virtual application? (I experienced it with the defaultApp).
Then your server port is probably wrong configured in the .OSD file.
Open the .OSD file;
Change:
<CODEBASE HREF="RTSPS://SERVERNAME:322/DefaultApp.sft"
Into:
<CODEBASE HREF="RTSP://THEOFIEL:554/DefaultApp.sft"
Refresh Server (using sftcmc.msc on the client)
And relaunch the application:
the error code means that your virtualized application services are off on your server ,open your server services and start them …….
i hope this helps you!
