[ovirt-users] Changing FQDN

Hi all, I am running ovirt 4.2.8 I did change ovirt engine FQDN using ovirt-engine-rename tool following https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/... Hosts FQDN is also changed and all seem fine apart from OVN connection and ImageIO proxy. About OVN, i just configured OVN and when I test connection I get: Failed with error Certificate for <new fqdn> doesn't match any of the subject alternative names: [old fqdn] and code 5050) about Imageio proxy when I test the connection I do get nothing. No error at engine.log or at GUI. Thus it seems that I have to generate/replace new certs. Is there a way I can fix this until I switch to 4.3 and eventually to 4.4 where it seems that this is handled from the rename tool? Thanks for any assistance. Alex.
