# Network setup for IT

> Enable HTTP/2 and allow CoLoop through your corporate network.

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:

| Host                        | Purpose                                                          |
| --------------------------- | ---------------------------------------------------------------- |
| `coloop.ai`                 | CoLoop website                                                   |
| `*.coloop.ai`               | CoLoop subdomains, including `app.coloop.ai` and `cdn.coloop.ai` |
| `img.clerk.com`             | Account images                                                   |
| `challenges.cloudflare.com` | Sign-in security checks                                          |

### 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.
