[ovirt-users] Issue with console since recently

Hi, We performed no updates on our infrastructure and since today, on some guests (not all), we see the following error in the libvirtd logs 140085012483328:error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:640: (process:375537): Spice-WARNING **: reds-stream.c:469:reds_stream_ssl_accept: SSL_accept failed, error=1 Other guests works fine. We are trying from Mac with remote-viewer and we use OS Version: RHEL - 7 - 4.1708.el7.centos OS Description: CentOS Linux 7 (Core) Kernel Version: 3.10.0 - 693.el7.x86_64 KVM Version: 2.10.0 - 21.el7_5.3.1 LIBVIRT Version: libvirt-3.9.0-14.el7_5.5 VDSM Version: vdsm-4.19.45-1.el7.centos SPICE Version: 0.14.0 - 2.el7_5.3 CEPH Version: librbd1-0.94.5-2.el7 And latest virt-viewer. Could anybody help us to the right direction? Currently, we cannot access the console of those VMs and we have no idea why. Thanks,Trefex
