curl: (6) Could not resolve host: mine.com
I resolved the issue by remotely power cycling the Pi that failed to resolve
the host. That worked.
I would like to understand what was going on here and how I can avoid the
problem in the future.
It is next to impossible to tell what happened without more details. The error
message suggests that when libcurl invoked getaddrinfo() to resolve the
hostname, it returned an error.
If this ever happens again, a first test would be to try other tools that
resolve hostnames using the similar mechanism (like for example "ping") and if
that shows the same problem we can probably assume the problem was in the
local resolver/DNS setup somehow.
