  • Extensions Interference: Ad blockers or VPNs disrupt protocols.
  • Proxy/Firewall Blocks: Network settings flag WebSockets as suspicious.
  • Outdated Edge: Missing security patches break compatibility.
  • Antivirus Overreach: Real-time scanning kills persistent connections.

Quick stat: Over 40% of WebSocket issues in Edge trace to extensions or cache, per recent developer forums. Ready to fix? Let's dive in! 👇
