Unable to pull metadata

[Kadaj81]

Hi all,

I've installed ABS and all is working fine, except fetching metadata. When I look for anything (cover, matching book and authors), always get back the error:
[Audnexus] Author ASIN request failed for Stephen%20King Error: getaddrinfo EAI_AGAIN api.audnex.us.

When I look up for covers or books, there is always no result, on any provider in the drop down.
I have no idea on how to solve this issue, and I really would like to have the metadata matching working.

Can someone help?
Much appreciated

My synology firewall was blocking the traffic. Added rule for port 443 and 53 UDP and now all is working.
