# Step 1: Determine how/why the site is being blocked
Info you need:
- Traffic source (private network, guest network, etc.).
- Traffic destination (domain, subdomain, URL, etc.)
- Blocked traffic reason (HTTP proxy, HTTPS proxy, WebBlocker, Blocked Sites, etc.)
You will likely get the traffic source and destination from the client. They may also attach a screenshot if they get an error showing why the traffic is blocked.
You can also search traffic monitor for the site domain to find why it was blocked.
