Thanks for getting back to me.

I think there is a misconception here. Using the engine builtin CA is more
secure than any other
CA, not less secure. You don't protect anything by using another CA.
What you really need to do is to import the engine CA certificate to your
browser, and this is also
required for communicating with the proxy.
Unless you know what you are doing, replacing the certificates with your
own is going to be
hard.
I set up a bastion host where I configured letsencrypt.
I copied the certificates over the ovirt engine machine and ran the
script "convert.sh" ( see attachement). ( still need to automate it to
handle certificate renew..)
Once this was in place, the test connection button ( in upload image UI)
gave me "green" "Connection to ovirt-imageio-proxy was successful."
This means that the proxy is configured to use the new CA, but this is not
enough
to upload. The proxy has its own certificates, and they must be signed by
the new
CA.
So to use your own certificates, you have to regenerate both the engine
certificates,
and the proxy certificates, and this process is not easy or documented yet.
If you created everything correctly, you need to configure the proxy to use
the new
certificates.
Finally, you need to restart ovirt-imgaeio-proxy, since it does not
support reloading
certificates or configuration changes yet.
I think the best solution for you is to use engine builtin PKI, managed by
engine-setup.
To "protect" your ovirt installation, add the engine CA to your browser
using this link:
https://my.engine/ovirt-engine/services/pki-resource?resource=ca-certific...
You save this file locally, and then you import this certificate into your
browser.
Using Chrome, you do:
1. go to: Settings > Advanced > Manage Certificates > Authorities
2. click "Import"
3. select the certificate
4. check "Trust this certificate for identifying web sites"
5. confirm
6. restart the browser
Here a copy of engine.log and ovirt-imageio-proxy log files. The ssl
paths
are dumped in the log file
Thanks for your support

Can you share the contents of:
/etc/ovirt-imageio-proxy/ovirt-imageio-proxy.conf
And the proxy log at
/var/log/ovirt-imageio-proxy/image-proxy.log
Showing the time of the error (failed to add image ticket to
ovirt-imageio-proxy.)
