[ovirt-users] Re: not able to upload disks, iso - Connection to ovirt-imageio service has failed. Ensure that ovirt-engine certificate is registered as a valid CA in the browser.

You are a saint and a scholar! This 100% fixed it for me. (Connection to ovirt-imageio service has failed. Ensure that ovirt-engine certificate is registered as a valid CA in the browser). oVirt version 4.4.5.11-1.el8 and using Firefox 78.9.0esr (64-bit) I tried to import the cert file; that worked just fine. But to no avail! I'm running an 'all-in-one' setup on CentOS 8 Stream, 4.18.0-240.22.1.el8_3.x86_64 I ran into some older posts with workarounds for various bugs, but most were fairly old and I suspected there was a cleaner way to get this working. This is it.
