Open the Network tab of the dev tools. 3. Right click on a request, and “Edit and Resend”. 4. Send. Actual results: 400 Bad Request, because the client certificate was not sent with the request. Expected results: The request should have succeeded.
Thanks for the report! > 1. Use a domain that requires a client-side TLS certificate. Do you have an example (online) page we could use to test this issue? Honza
