Connetion Trouble between UCS and Knowledge Manager

filippe_macedo · November 21, 2011, 6:07pm

Hi There,
My name is Filippe, I’m new here!

I have a trouble between Knowledge Manager and UCS!
When i try to connect the Knowlege manager, I got the following error:
“Contact Server Connection Failed”
This connection is through a server using a NAT IP

But, it is wierd becouse, I did the Installation(knowledge manager) in my computer and it worked!
I saw logs of knowledge manager and there is a message:
“com.genesyslab.icc.api.contactserver.PersistentException: UCS connection failed”

Look this:
“com.genesyslab.icc.api.contactserver.PersistentException: UCS connection failed

Hi Filipper,

Error message says that remote host refused the connection (see extract below). Please check there is no firewall blocking the connection including Windows Firewall running on the server.

Caused by: java.rmi.ConnectException: Connection refused to host: SVTT102CTO; nested exception is:
java.net.ConnectException: Connection refused: connect

Hi Filippe,

What version of UCS and Java do you use? Do you have option ‘ucsapi-duplex-mode’ enabled on UCS?

R.

filippe_macedo · November 25, 2011, 1:01pm

Hi René

The Java Version 1.5 and UCS is 8.0!!
Duplex mode is enabled!!
I’m yet trying to solve it!!

Thanks again!!

filippe_macedo · November 25, 2011, 2:15pm

heyyyyyy!!!
PROBLEM SOLVED!!!

I JUST RESTART UCS BEFORE CHANGE THE DUPLEX-MODE OPTION, AND CHANGE THE HOST CONFIGURATION(VERY IMPORTANT)!
THIS TROUBLE IS BECAUSE I AM USING A NAT IP!!!

BUT ANYWAY!!
THNKS RENÉ!!!

Hi Guys,

facing same problem Filippe solved way back in 2011, I decided to reply to the very same topic. Let me know if it’s better to start a whole new topic.

As I said, same problem… refused connection to UCS when logging to Knowledge Manager. ‘ucsapi-duplex-mode’ is enabled on UCS and, following what Filippe did, tried a telnet and everything seems okay. Tried a restart of UCS as well.

What am I missing?

Which version of UCS?
If you have 8.5.309 or higher there is a known bug preventing KM to connect.

Sosy · September 5, 2019, 8:03am

Hi catanirex, thanks for your reply!

UCS version is 8.5.300.35… so unfortunately it’s not our case… and Java version is 1.7 by the way, in case it helps.

Let me know if I can provide to you more infos to better understand the issue.

Thanks!

Sosy · September 5, 2019, 11:25am

Hi catarinex,

Sorry but did u mean 8.5.300.09? ??? 8.5.309 it’s not a thing so that could explain the issue.

What I cant explain at this point is that we upgraded to .35 on and then used the KM no problem on the day after. And now we have no connection.

Locally at server works?
Maybe your problem is just a network issue like a firewall or something

Sorry for confusing with version number - remebered it wrong… BTW - Your version is not available any longer from Genesys…

The bug I mentioned is fixed in the version released yesterday:

"UCS support for RMI-based applications such as Knowledge Manager, GAD, ISDK and GIS is restored. Note that you still need to enable RMI support—option enable-rmi—in UCS options. (ESR-14549) "
