Remediation

Identify the impact area by pinging a public DNS server and your private DNS server servicing this
Prisma Access
location. If this behavior affects the public DNS, contact Palo Alto Networks Customer Support Portal.
If you see this behavior only on a private DNS, identify whether this DNS server is reachable from other
Prisma Access
locations or from another site within your on-premises infrastructure. If the server is reachable from other
Prisma Access
locations or on-premises, but not the impacted site, proceed to step 3.
Collect
traceroute
data to help identify the network path for this
Prisma Access
location. Based on the
traceroute
, validate the IPSec tunnels for the target data center or branch.
If the
traceroute
doesn't help you identify the stoppage, contact Palo Alto Networks Customer Support Portal.
