1. Configure corporate firewalls and proxies
   • SSE uses a single, long-lived HTTP connection with a text/event-stream content type. Security tools often misinterpret this as a continuous download and block it.
   • Allowlist required Salesforce domains including the Event Router endpoint:

     https://{scrt-url}/eventrouter/v1/sse

   • Disable chunked-encoding and buffering on proxies or VPNs for Salesforce traffic to maintain uninterrupted message streaming.
   • Bypass antivirus inspection by turning off “block malicious downloads” and deep-packet scanning for Salesforce traffic.
     
     
2. Verify VPN contexts
   • Disconnect from the corporate VPN temporarily and test the chat.
   • If the issue resolves, adjust VPN configuration to allow continuous SSE connections.
     
     
3. Exclude Salesforce domain from SSL inspection
   • If SSL inspection is enabled, it intercepts SSE streams and blocks real-time responses.
   • Add this domain to your SSL Do Not Decrypt policy (e.g., in Netskope):

     flexerasoftware.my.salesforce-scrt.com

Outcome

After implementing these changes, chatbots embedded across Flexera product consoles and the support community display real-time support responses reliably.
