By default, only logs by Google, Let's Encrypt, and Trust Asia are available for live log scanning. The rest of the logs have not explicitly configured response headers related to the CORS policy. Some unavailable logs can be scanned after switching off CORS same-origin policy and/or other security features of your browser, such as certificate verification. Disabling security features of your browser must only be done in a safe environment.

Debug output can be found in the browser console.
