We are monitoring an externally hosted application https://<website-name> from our OPMS within our internal network. Most of the time the results on the check are OK, however not always.
In the results of a failed check, We find that the IP was resolved properly:
CA App Synthetic Monitor Checkpoint www.<server-name> X0X0 IN A xxx.xxx.xxx.xxx
Under Domain Analysis, there is a message:
Nameserver error on <server-name>: Cannot connect to the name server.
We would like to understand when OPMS (HTTPS monitor) performs the domain analysis. Is it only after a monitor check fails?
Does the message "Nameserver error on <server-name>. Cannot connect to the name server." means that OPMS cannot connect to <server-name> or our DNS cannot connect to <server-name>?
