Hi dev,
Hope you are doing good.
Check the below notes along with the network administrator to ascertain that there are no network related issues as this is a clear case of the same
#124562 Hostname resolution problems (DNS timeouts)
#500235 Network Diagnosis with NIPING
#413330 Network timeout
If you run the niping tool at the time the issue occurred, it should check the whole network and report the error.
Thank you!
