https://github.com/XTLS/Xray-core/issues/4348#issuecomment-2637370175 Local received SNI was sent by browser/app. In freedom RAW's `tlsSettings`, set `"serverName": "fromMitm"` to forward it to the real website. In freedom RAW's `tlsSettings`, set `"verifyPeerCertInNames": ["fromMitm"]` to use all possible names to verify the certificate.
