3664311 - CTI iFrame Local Access Blocked by Chrome 141 in SAP Service Cloud (Live Activity/Agent Desktop)

• Starting with Google Chrome version 141, a new security restriction disables local network access for iframes by default.
• This change could affect SAP Cloud for Customer (C4C) users whose Contact Center (CTI) solutions connect to local servers via iframe in the Live Activity view.
• Customers embedding local Contact Center widgets (e.g., Genesys) in C4C via iframe are now unable to establish the connection, resulting in CTI login failures and inability to accept calls.

• SAP Service Cloud Version 2
• SAP Sales Cloud Version 2
• Live Activity
• Agent Desktop
• Google Chrome version 141 and above

1. Ensure access to a local intranet URL is available.
2. Use Chrome 141 with the "Local network access restrictions" option enabled.
3. Click on the C4C Phone icon and check whether the Contact Center iframe can connect to the Contact Center.

This behavior is caused by a third-party change introduced by Google Chrome, which restricts iframe access to local resources unless explicitly allowed by browser policy.

• To allow iframe access to local servers in Chrome, administrators must configure Chrome Enterprise Policies on end-user machines.
• This configuration must be deployed and maintained by the customer's IT team. It is outside the scope of SAP application settings.
  1. Create or Edit Chrome’s Policy File:
     • Windows: Use Group Policy or a .json file.
     • macOS: /Library/Managed Preferences/com.google.Chrome.plist
     • Linux: /etc/opt/chrome/policies/managed/policies.json
  2. Add the Following Configuration:
     {
       "LocalNetworkAccessAllowedForUrls": [
         "https://your-allowed-domain.com"
       ],
       "LocalNetworkAccessBlockedForUrls": [
         "https://your-blocked-domain.com"
       ]
     }
  3. Apply and Restart Chrome:
     1. Save the policy file.
     2. Restart Chrome.
     3. Visit chrome://policy to verify policies are correctly applied.
