Hi folks, From time to time, the button "accept the risk and continue" for a selsigned certificate (= generated locally using openssl, mkcert tools, etc) appears and sometimes not. When the button is not displayed, then we got as error "SEC_ERROR_UNKNOWN_ISSUER". My question is then: "When SEC_ERROR_UNKNOWN_ISSUER is returned for selsigned certificate or not ?" Is there a way to debug and got a more verbose message to troubleshoot ? Many thanks Charles M.
