[SRX] Common issues causing enrollment failure for SKYATP

Verify that the SRX/vSRX is running on the supported OS version. Please check the Sky Advanced Threat Prevention Supported Platforms Guide.
Verify the DNS can resolve Sky ATP servers to an IP address on the SRX. The following domain names should be resolvable on the device.

For US - amer.sky.junipersecurity.net & srxapi.us-west-2.sky.junipersecurity.net
For EU - euapac.sky.junipersecurity.net & srxapi.eu-west-1.sky.junipersecurity.net
For Canada - canada.sky.junipersecurity.net & srxapi.ca-central-1.sky.junipersecurity.net
For APAC - apac.sky.junipersecurity.net & srxapi.ap-northeast-1.sky.junipersecurity.net
Enrollment - ca.junipersecurity.net & va.junipersecurity.net
Verify the device time is correct. It is recommended to have an NTP to sync time.
Verify routing from RE and PFE to SKY ATP cloud servers. Ping from the firewall to the server in the region you are enrolling to confirm the connectivity.
For US:
root@srx> ping connect.us-west-2.sky.junipersecurity.net
For EU:
root@srx> ping connect.eu-west-1.sky.junipersecurity.net
For Canada
root@srx> ping connect.ca-central-1.sky.junipersecurity.net
For APAC
root@srx>ping connect.ap-northeast-1.sky.junipersecurity.net
Verify the ports 80, 8080 and 443 are open to the internet from the firewall. You can telnet from the SRX on these ports to the SKYATP servers.
To verify that different daemons are working properly on the firewall, please check the following connectivity:
1. For aamw-ca daemon, verify connectivity to ca.junipersecurity.net port 8080
```
root@srx% cd /var/tmp
root@srx% fetch -v -o cacert.testfile "http://ca.junipersecurity.net:8080/ejbca/publicweb/apply/scep/SRX/pkiclient.exe?operation=GetCACert"
```
  This will download a file from the CA server. Some firewalls can block this URL because it contains '.exe'. It is normal to receive an HTTP 400 Message. 'Timeout' indicates there is a connectivity issue which needs to be fixed.
2. For aamw-secintel-ca, verify connectivity to va.junipersecurity.net port 80
```
root@srx% cd /var/tmp
root@srx% fetch  http://va.junipersecurity.net/ca/SecInteljunipersecuritynetCA.pem
```
3. For aamw-cloud-ca daemons, verify connectivity to va.junipersecurity.net port 80
```
root@srx% cd /var/tmp
root@srx% fetch http://va.junipersecurity.net/ca/SecInteljunipersecuritynetsubCAforCloud.pem 
```
When you enroll an SRX/vSRX Series device, the ops script installs two CA certificates: one for the client(SRX/vSRX) and one for the server(cloud). Client-side CA certificates are associated with serial numbers. Use the CLI command to get your device’s certificate details and serial number.
```
    show security pki local-certificate
    show security pki ca-certificate
    show security pki crl detail
    show security pki local-certificate detail 
```

Verify that the services are running on the firewall:

show services advanced-anti-malware status

Note: Ideally the output should be:

root@srx> show services advanced-anti-malware status

Server connection status:
Server connection status:
  Server hostname: juniper.cloud.com
  Server port:     443
    Control Plane:
      Connection Time: 2017-05-25 02:30:20 UTC
      Connection Status: Connected
    Service Plane:
      fpc0
        Connection Active Number: 16
        Connection Failures : 41

If all of the above points are correct and the enrollment still fails, please run the diagnostics and contact JTAC for further assistance.
