Hi Konstantin, I was reading your post and wonder that maybe you could help with a similar issue as well. I also have a problem with certificates and iso/file upload (plus an additional but probably connected noVNC case) but on a Windows 11 box. The thing is that when I run admin portal (this is a hosted-engine setup) from a Linux box, one of the KVM hosts, everything (both upload/noVNC) is working fine, but when run from a Windows box... it doesn't. On Linux, I just added the ovirt certificate to the browser root trust store. On Windows, the same setup is not working. It seems that for Chrome and Edge the root trust stores for browsers and the OS itself are the same, for Firefox there is a difference as it has - as I understand - its own root trust store. Either way, after adding certificates to these stores, I can only get the browser not to flag the connection as insecure, but both upload and noVNC are not working. As I have mentioned, this problem occurs only under Windows, not Linux. I would appreciate any help. Thanks and best wishes, Adam Dnia 13 kwi 2023 18:32 "Volenbovskyi, Konstantin" <Konstantin.Volenbovskyi@haufe.com> napisał(a): Hi, I think that you might simply need to restart ovirt-imageio-proxy service because it potentially uses the old certificate/different from the one used by ovirt-engine service. And in general I would suggest to troubleshoot that using https://myhomelab.gr/linux/2020/01/20/replacing_ovirt_ssl.html You should be able to troubleshoot that using 'curl'/openssl commands: in the way that it relies on system trust of root CAs and trying engine URL vs. image-proxy URL might reveal more information. This might mean that you ignore browser (and its own store of certificate/trust settings...), but start from point that there is storage of root CAs and trust exists because HTTPS endpoint provides certificate chain: server certificate plus certificate of sub-CAs (if needed) that is ultimately signed by root CA that trusted by your system.

Hi every one. I was having the same problem with Ovirt 4.5.7. So I downloaded the CA .pem at http://<ENGINE-FQDN>/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA. Then I installed it in Firefox and restarted ovirt-engine. It worked.
