How to Access the Kredin Portal When Using Citrix

⚠️ Applies to: Users attempting to log in to konto.kredin.cloud from a Citrix environment, but experiencing issues such as login failure, incomplete page loading, or error messages.

⚠️ Symptoms of the Issue

When trying to log in to the Kredin portal via Citrix, the following issues may occur:

• The page does not load or shows error messages during login
• The login button does not respond
• The browser displays messages like “Access to XMLHttpRequest has been blocked by CORS policy” or “WebSocket connection failed”

These issues usually do not occur when using Kredin outside of Citrix, for example through a standard browser on a local machine.

💡 Cause

Citrix environments are often configured with additional network restrictions, such as:

• Blocking certain types of network requests, like WebSocket connections
• Preventing preflight requests (CORS preflight) from the browser before data is sent to Kredin’s API
• Disallowing traffic on specific ports, such as port 6001 used for real-time services (WebSocket)

✅ Solution

To ensure Kredin works properly within a Citrix environment, the IT department or system administrator must:

1. Allow traffic to the following addresses:

• https://api.kredin.cloud
• https://konto.kredin.cloud
• wss://ws.kredin.cloud:6001 (WebSocket connection for notifications and real-time updates)

  2.  Allow the following outbound ports from the Citrix environment:

• Port 443 (HTTPS) – required for standard traffic
• Port 6001 (WebSocket over TLS) – used for real-time services

  3. Set exceptions in any firewall or proxy:

If a proxy or DPI (Deep Packet Inspection) solution is used, make sure it does not block or modify CORS or WebSocket traffic

👤 What the User Can Do

Contact your IT department and refer them to this article

Test whether it works from a standard browser outside Citrix – this confirms whether the issue is specific to the Citrix setup

👉 Temporary Workaround

If the Citrix environment cannot be adjusted immediately, Kredin can be accessed using a local browser (outside Citrix) as a temporary workaround.
