I've tried to recover my account via Chrome and Safari.

Chrome I received the email, then typed in my details being my name and my WebID URI and it failed to issue me a cert. but gave me access to my account via warp. (no cert)

Wasn't sure if it was adblocker or something; so tried with safari, and it issued a cert; but it seems the URI is incorrect. (images attached)
