Hi, I have setup the OCServ0.9.2 following guide and during the startup I got below erros: listening (TCP) on [::]:4443... listening (UNIX) on /var/run/ocserv-conn.socket... listening (UDP) on 0.0.0.0:4443... listening (UDP) on [::]:4443... ocserv[24701]: main: initialized ocserv 0.9.2 ocserv[24702]: sec-mod: error loading file '/usr/local/etc/ocserv/serverkey.pem ' ocserv[24702]: GnuTLS error (at sec-mod.c:590): Error while reading file. ocserv[24701]: main: tlslib.c:613: error loading file '/usr/local/etc/ocserv/server.crt.pem ' ocserv[24701]: main: tlslib.c:692: error loading the certificate or key file At first, I think the key files not created correctly, but after I tried to create key files several times, still got the same error message. Does anyone can give your advice on this issue? Thanks a lot! Young
