Connect DNS lookups hang indefinitely if there's no response #142

Closed MKrupauskas closed 4 months ago

MKrupauskas commented 4 months ago

The DNS host provider uses net.LookupHost which doesn't timeout (it just hangs indefinitely) even when the DNS resolver is unreachable.

The expected behavior would be that after 3 seconds (proposed but open to feedback) the DNS lookup times out and fails.

This will be done by using Resolver.LookupHost.
