If you see Network change required, send this page to your IT team.

​
1. Enable HTTP/2 and streaming

CoLoop requires HTTP/2 or newer for reliable chat and live updates. Apply these settings to all paths on app.coloop.ai:
  • Enable HTTP/2 (h2 via TLS ALPN) through your proxy, VPN, and web filters.
  • Allow Server-Sent Events (text/event-stream) to stay open and deliver events without buffering.
  • If TLS inspection blocks HTTP/2 or streaming, exempt app.coloop.ai from inspection.

​
2. Allow the required hosts

Allow outbound HTTPS on TCP 443 to these hosts:

​
File storage

Allow both hosts for each region your organization uses. Preserve signed URLs, including query parameters. Allow GET, HEAD, PUT, and OPTIONS.

​
3. Verify the connection

  1. On the affected computer, reload CoLoop with the usual network, VPN, and security software active.
  2. In Chrome or Edge, open Developer tools → Network and enable the Protocol column. Requests to app.coloop.ai should show h2 or h3.
  3. Send a chat message. Confirm the response streams and CoLoop stays responsive.
If the issue persists, contact support.
