Accessing pub app and getting error message "An error occurred while making the requested connection. "

Medium Priority
Last Modified: 2012-05-11

I'm evaling XenApp6 and cannot seem to get past the following error message "An error occurred while making the requested connection." whenever I launch any pub app.

Here is my setup

1 - Win2008 R2 x64-bit (XenApp6, Web Interface v5.4.0.59)
1 - Win2008 R2 x64-bit (XenApp6 used for published apps)
1 - Win2008 R2 x64-bit (XenApp6 license server with eval licenses)

I have everything installed per the XenApp6 requirements but must be missing or overlooking something that prevents me from accesing these pub apps.


Watch Question

Few questions. Are you accessing through web interface? Are you sitting inside or outside the network? Has this ever worked? What XML port are you using? (default is 80). Does web interface exist on the xenapp server?

I've seen this error usually from web interface when the XML config on web interface is not configured correctly. I've also seen this error when web interface is on the same box as xenapp and the XML port is configured to share port 80 with iis. Sometimes the listener is grabbed by IIS and doesn't allow XML to work properly.

In that case I would change XML to port 88. Reconfigure web interface to use port 88 as well. There is a powershell command to change the port to 88.



I appreciate your help.   We are using Web Interface and it is installed on a XenApp6 Server and when we installed XenApp 6 we told it to use port 85 for everything related to Citrix.   It has not worked since day 1 of the install.

Where can I check to make sure XML is using port 85?  I thought it was inside Web Interface but if there are other palces I need to check on the server let me know.

Do a netstat -an on the xenapp server and see if its listening on port 85.

it should look like this

TCP               LISTENING


I ran the "netstat -a" command as you said from all Citrix XenApp servers and they all had the following

 Proto  Local Address          Foreign Address        State
 TCP             ServerXXX:0          LISTENING

All seems to well on the port side.   Can you think of something else I can try?

ok, So it seems that the XenApp server is listening on the right port. Can you please verify your web interface settings? If you can take a snapshot of the XML setting and of the STA settings.

Also, are you accessing the environment over the WAN or over the LAN currently?

Also, check the eventvwr on the server that is running the web interface. What is the error in there?
