## How do I add URLs as trusted domains?

Check with your IT administrator to see if your company has blocked the URL domain for the 8x8 cluster. Your company's IT department may have configured the router or changed the registry to block some websites. If so, you must allow or add the URL domain that has your **8x8 Contact Center** tenant (such as `https://vcc-naX.8x8.com/AGUI/login_ns_sso.php?tenant=yourtenantname`) to access the 8x8 URL domain.
