Listeners > Listener not booting when certificate is unreachable

While attempting to update Carapace with the branch 410-http2-enable-http2-h2, Carapace fails to start due to this error:

The certificate in question, which is being loaded, is actually in an UNREACHABLE state, meaning there is no certificate, or there may not be a certificate available for this domain.

Therefore, we need to ensure that we load ONLY certificates that are in the AVAILABLE state.

I get same error for another certificate but it's available:
