In certain situations (most frequently when previewing a test), a customer’s corporate network can prevent users from accessing UserTesting domains. Adding certain domains to an Allow list (sometimes called a "Whitelist") can overcome this issue.
We find that some access issues, including most preview-related errors, are due to corporate network restrictions. We suggest speaking to your IT department and asking them to add the following domains to an Allow list:
- The IPs from Fastly to your Allow list. Fastly is the CDN (content delivery network) that UserTesting uses.
- The IPs from Okta to your allow list. Okta is the identity/authorization provider that UserTesting uses.
