DNS_PROBE_FINISHED_NXDOMAIN

I am facing DNS problem with my OWA service. At first the service was working fine but now i am facing a error that says DNS_PROBE_FINISHED_NXDOMAIN (Server IP address could not be found). But internally on my LAN I am about to open the OWA without errors. I published the OWA through XG 210. Source Zone-WAN, Allowed Clients Networks-Any, Destination Host/Network- ISP IP Address, Services- HTTPS, protected servers-myexchange server, Protected zone- LAN.

Hi Chimwemwe Mtonga

Could you please share the error screenshot?

Please also capture drop packet for port 53 and the IP of the OWA server- https://community.sophos.com/kb/en-us/127111

As pointed out internally i am able to access it and outside it can only be accessed by domain name not IP Address.

Hi Chimwemwe Mtonga

Could you please let me know here about your DNS entry for your OWA server?

How DNS flow will work?
