Like the title says. Root Certificate gets generated but not the host certificate. No OprenVPN-server can be started (greyed out) and OpenVPN gUI says "TLS handshake failed" whether tls key is available or not). The Certificate generation problem was fixed in the last few ipfire versions but with the fresh installed version 2.29 the error is still there and no new certificate can be created without an error.
