Hi @astrava,
The hostname you provide MUST be resolvable both from inside the Kaltura server and from any machine you’ll be using the kaltura API/web I/Fs and player embeds from.
According to your output, the curl command trying to verify the hostname is accessible over HTTP failed.
You need to understand why that is.
If the hostname IS resolvable then something must be wrong with your Apache configuration. If that’s the case, what’s the output for:
# apachectl -t -DDUMP_VHOSTS
?
