I have unbound installed on Centos 7 arm architecture. http://mirror.centos.org/altarch/7/isos/armhfp/ It seems to work fine but I keep getting this error when using unbound-control: # unbound-control stats error: SSL handshake failed *:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed:s3_clnt.c:1172: Any ideas?
