Error: There is no Citrix XenApp Server configured on the specified address : [Socket error 10060]
Solution:
Mostly this is port problem. If you are connecting to storefront url directly without netscaler, from user’s device, open 2598 and 1494 ports to the VDA servers. Without this, you will see “Connection in progress…” bar but it wont move to “connection established Negotiating capabilities…” step.
After a min, it shows “There is no Citrix XenApp Server configured on the specified address : [Socket error 10060]” error.
In a Citrix NetScaler appliance, the Management CPU is responsible for handling management tasks such as configuration, monitoring, and reporting. On the other hand, the Packet Engine CPU is dedicated to processing network traffic, including tasks like load balancing, SSL offloading, and content switching.
The Management CPU is used for handling administrative tasks and does not directly impact the processing of network traffic. It is responsible for managing the configuration of the NetScaler appliance, monitoring its performance, and handling administrative tasks such as logging and reporting.
Issue:
When users click on the app, it loads the receiver, starts the dialog box which says loading profile, scripts, getting ready etc and the progress bar completes. Just before the application launch, it disappears. Session is created on the server but application wont launch on user’s device.
Error:
The Citrix Universal DLL injection driver has encountered an unexpected error.
Event id: 1005 on the app server(VDA server).
Solution:
Restarting the app server will temporarily fix the issue.

Introduction CVE-2023-4966 and CVE-2023-4967 are critical and high-severity vulnerabilities, respectively, that affect NetScaler ADC and NetScaler Gateway from Citrix. These vulnerabilities can be exploited to disclose sensitive information or cause a denial of service (DoS) condition on affected devices.
CVE-2023-4966 is a sensitive information disclosure vulnerability that can be exploited by an attacker to remotely access sensitive information from vulnerable NetScaler ADC and NetScaler Gateway appliances. This information may include usernames, passwords, cookies, and other authentication credentials.
Issue After logging into netscaler gateway, we received “Http/1.1 Internal Server Error 43531” error. Upon looking at the configuration, STA server in the netscaler gateway is marked as down. DDC and storefront are installed on same server. Under traffic management/lb vip was also marked as down and the storefront service group in that lb vip was down. All the probes sent to that STA/storefront server were not successful. TCP-default monitor was attached to the storerfront service group.
Issue:
upgraded netscalers to 13.1 49.13nc version. Post upgrade, when netscaler gateway vip is accessed from browser, it showed “Http/1.1 Internal Server Error 43549” error.
Solution:
If you are using AAA auth profile, you should have authentication vserver, and advanced authentication policies in it. Check if all the required advanced authentication polices (LDAP, RADIUS etc) are present in authentication vserver.
In our troubleshooting, we found that advanced authentication policy was missing in the authentication vserver.
