Issue
The DNS server does not
respond to a DNS lookup.
The AP receives the DNS
server through DHCP but
it cannot reach or ping
the Juniper Mist™ cloud.
When the AP gets an IP
address from the DHCP
server, the AP tries to
reach
ep-
terminator.mistsys.net. If
the DNS server is unable
to resolve this URL, the
AP cannot connect to the
cloud.
Steps to Troubleshoot
•
Connect a laptop on
the same VLAN or
network, and try to
ep-
resolve the URL
terminator.mistsys.net
to an IP address by
nslookup
executing the
command at the
command prompt.
C:\Users
\username>nslookup
ep-
terminator.mistsys.ne
t
Server: dns.google
Address: 8.8.8.8
Non-authoritative
answer:
Name: ep-term-
production-1584483204
-1989267174.us-
west-1.elb.amazonaws.
com
Addresses: 52.9.76.55
13.57.102.113
Aliases: ep-
terminator.mistsys.ne
t
nslookup
•
If the
command cannot
resolve the URL,
explicitly add the URL
to your DNS server.
•
If the issue is still not
resolved, check the
firewall and proxy logs
