CAD 8.5 Error: Unable to download file. Could not open request

I am having this error when I try to open the CAD after installation.  Initially it said that it is looking for updates but then error message popped up.  When I click ok on this message, I get another message "A licensing error has occurred. Please try again in five minutes.  If the problem persists, please see your log file or contact System Administrator for details."  The server is on 10.x.x.xnetwork.  When I installed the application on the PC part of the same subnet, it works fine.  However, issue occurred when I installed application on a PC part of 172.x.x.x network.  Is there anything on the firewall I need to worry about to allow this connection?

Thank you Hang!  Is there any documentation on this I can read to understand it better?

Hi,

1. Please ensure " Cisco Desktop License and Resource Manager Service " on your UCCX node is running. Try restarting it & see if it helps.

2. From Agent PC, you should be able to telnet the UCCX node with port 3000, if you are not able to then you need to ensure that it's opened in Firewall between them if any.

3. Turn off the Windows firewall on agent PCs.

4. Restart of server & CTI manager service does help but not always.

5. As a final resort if nothing helps, license rehosting could be also an option.

Cisco TAC had seen this issue quite often & above are the typical findings.

Hi,

Please check the engine MIVR logfiles for the errors:

-If not enabled then do the same, recreate the issue and collect the files from RTMT, the error should display similar to the below, I had a similar TAC case sometime back

Socket:Socket[addr=...port=3739,localport=...] invokeID:3 failureCode:CF_GENERIC_UNSPECIFIED errorCode:88001 text:Unable to login agent due to problems in JTAPI or CM in CTI Server's message queue

-if you are seeing the same, restart the CTI manager and it should work as expected

Let me know if this helps

Thanks,

Re: CAD 8.5 Error: Unable to download file. Could not open reque

Does this happen as soon as you attempt to start the agent?

I ran into this error recently (assuming your license service is running and licensed) - it turned out the calabrio LDAP structure on the UCCX server was corrupted.  If you have a TAC case opened, ask them to verify the Calabrio LDAP integrity on the server for you using an ldap browser.

Also if it is corrupt, the server does hold backups of the ldap structure that you can use to restore the structure. 

This LDAP info is what the server uses to push the CAD configuraiton to the Agent.

Re: CAD 8.5 Error: Unable to download file. Could not open reque

Just to let everyone know that this was due to routing issue for the subnet 172.x.x.x.  It didn't know how to get to the server vlan.  Once the route was added for the server vlan, it started working.

Thanks for everyone's input
