robin154 Hello, when i will activate Webauthn for Admin or an Mailbox User i get the error invalid root certificate. I get the error on every browser but my main browser is google chrome. i run adguard but it also not working when i deactivate it.
robin154 esackbauer OTP and the WebUI is working. I don’t get an cert error. But i will activate WebAuthN. I have changed the Hostname 1 or 2 years ago, on my old hostname i had WebAuthN working properly.
