DNS problem: query timed out looking up A

Help
15

Not surprised. It worked. Here is what i've done.

  1. Created zone for domain in a different datacenter with same DNS settings
  2. Added A record points to my problematic server
  3. Changed nameserver's to other server
  4. Installed SSL on my server. Success.

After this i've changed NS records back to my server and able to work with domain also able to renew SSL through auto installer UI

So now the question is why Letsencrypt can perform a DNS lookup for A record on my server. I've checked most known web sited for my record all works fine except MXToolbox.

MXToolbox result are a bit confusing too, may throw an error "Not able to get a response from name servers within timeframe"
