Last error for IPv4: DNS query for openapicenter (A) returned an error response (Server Failure). Previous error for IPv6: DNS query for openapicenter (AAAA) returned an error response (Server Failure). My /etc/resolv.conf is search test.svc.cluster.local svc.cluster.local cluster.local nameserver 169.254.20.10 nameserver 192.168.0.10 options ndots:3 timeout:1 attempts:2

[WyriHaximus]

have you tried using the FQDN? openapicenter.test.svc.cluster.local should work. As we haven't implemented the search option in the DNS packages IIRC.

@Chrisdowson Thanks for filing this PR!

As @WyriHaximus pointed out, it looks like you're affected by lack of support for the DNS search option. You can try using a FQDN as a work around in the meantime. We keep track of this feature request in reactphp/dns#158, perhaps you can help contribute to this ticket?

The PR itself should probably target the underlying DNS component instead of the higher-level HTTP layer. Also note that using gethostbyname() is inherently blocking and accordingly not something we could use in a non-blocking application. See the above DNS ticket for some further details.

I hope this helps! I believe this has been answered, so I'm closing this for now. Please come back with more details if this problem persists and we can always reopen this 👍
