Cannot Log in to Citrix

I have a Citrix server running XenApp 6.5 on one farm, no gateway, etc.  Either after I installed one published app or re-started the server, users can no longer log in to the server.  Using my login, I receive the error:

Please verify your user name and password and try logging on again. If you cannot log on, contact your help desk.

After looking at the event log on the Citrix Server, I see three events tied to the failed login:

Informational Event ID 30401

Site path: C:\inetpub\wwwroot\Citrix\XenApp.

A socket has been forcibly destroyed by the transaction layer. [Unique Log ID: 6ca3841d]

For specific information about this message, see the Web Interface documentation at

Error Event ID 30024

Site path: C:\inetpub\wwwroot\Citrix\XenApp.

The XML document sent by the Citrix servers could not be processed because it contains invalid XML. This message was reported from the XML Service at address . The specified Citrix XML Service could not be contacted and has been temporarily removed from the list of active services. [Unique Log ID: 962b2088]

For specific information about this message, see the Web Interface documentation at

Error Event ID 31003

Site path: C:\inetpub\wwwroot\Citrix\XenApp.

All the Citrix XML Services configured for farm XXX Farm failed to respond to this XML Service transaction. [Unique Log ID: d6fdb4dc]

For specific information about this message, see the Web Interface documentation at

I searched through the Citrix forums and looking up the event ID's trying different suggestions.  I verified the XML port (8080) is the same in the web interface as in the AppCenter, tried unregistering and re-registering with a different port, etc.  

I cant find anything else to try.  I'm not a Citrix pro but I can stumble my way through it.  Does anyone have any troubleshooting or tips to try?

1. Request you to install all the recommened hotfix for the Xenapp available in Citrix site
2. Check XML port both on the web interface and also on the XenApp server. If same problem, change XML port at both the places.

Check the XML service status. If it is in stopped state. Start it.
If it is already in started state, unregister the XML service and register the service with r8080 instead of r80. Follow below article,

Change port number to 8080

Thanks for the post but I have tried that a couple of times already.  Does not change anything.  The XML service is running.  I've also tried changing ports to 8081 instead of 8080.

Can you try replacing the XML hostnames in the Web Interface configuration with their IP addresses?

If this resolves the issue, then there is a problem in your environment resolving the hostnames of the XML servers.

I ended up rolling back the Citrix Server to the last good backup and it is up and running since I couldn't keep it down any longer.


Thanks for the suggestion.  I did not try that.  Not sure why it would be since I have everything running on one Citrix Server.


I did try downloading the hotfix rollup package from Citrix.  Seems to have made it worse since after I did that, I couldn't even get the web interface to load.

Tried changing the XML port in both locations from 8080 to 8081.  The port change seemed to work but still no luck.
