What does this mean?

Agilico Connect uses WebSockets (via SignalR) to maintain a persistent, live connection to our servers. This is how the app instantly knows when you are receiving an incoming call or when a colleague's presence status changes to "Busy". If this fails, the app may appear online but won't ring for inbound calls.

How to fix it:

  1. Allow WebSocket Traffic: Some strict firewalls block HTTP Upgrade requests, which are required to establish a WebSocket. Ensure your firewall or proxy permits WebSocket (ws:// and wss://) traffic.
     
  2. Disable SSL Inspection: If your corporate firewall uses SSL/TLS Decryption or Deep Packet Inspection on HTTPS traffic, it will break the WebSocket. You must exempt *.agilicoconnect.co.uk from SSL inspection.
     
  3. Antivirus Web Shields: Check if local antivirus software (like Avast Web Shield or Bitdefender) is intercepting web traffic and blocking the persistent connection. Try temporarily disabling the web shield to test.
