Hi all,

 

I was trying to create a package using package and deploy tool and getting below error. My environment has a single standalone server. I have checked if ports 5555 and 5252 are being used by any other process and they are being used only by K2 Host service. Any help?

 

"Error Receiving Buffer:An existing connection was forcibly closed by the remote host"

 

Details:

Hi Pnelli


 


See the possible solution below:


 


1. if this problem started after the upgrade so something might have gone wrong with the configuration.
then do a reinstall of K2 and this should resolved the issue.


 


2. In order to clean the K2 production server, during a time were a minimum of user are connected, we advise to:


    Remove the service instance with system name.


    Redeploy the package and do an attention about to select "Use existing service instance" for the service instance 


 


3. Port 5555 is the correct and default expected port that you should use for Package and Deployment.  The following gives a list of ports and what they are used for:

Hi pnelli;


 


Could you please try installing the latest fix-pack on your environment and see if the error still persists, and kindly let us know if it does.

Hi pnelli,


 


May I kindly ask have you tried restarting the K2 service, and performing an IISRESET, if that has been covered and the issue is still present it might be that your K2 web-facing applications are all missing some connection strings.


So you may want to check if your web.config is using the correct hostnames.


 


Also please have a look at the following KB articles which are central to the same issue you are facing, they were, however, published for K2 4.7 (black pearl) but the resolutions contained within them should apply to your environment.
