Troubleshooting
Whenever troubleshooting a connection issue, the following questions should be answered to 
ensure the configuration is correct.
1.
Is the printer connected correctly via Wireless or Ethernet?
2.
Does the printer have a valid IP address?
3.
Can I ping the printer’s IP address from a device on the same network as the printer?
4.
Is the remote server URL in 
weblink.ip.conn1.location
 correct and does it point to the 
remote server that is configured for weblink functionality?
5.
Can you connect to the location defined in the 
weblink.ip.conn1.location
 setting via a 
browser?
6.
Is the remote server I am attempting to connect to outside the corporate firewall?
7.
Can the URL specified in 
weblink.ip.conn1.test.location
 be accessed?
If this is the case, talk with your administrator about altering restrictions for accessing 
HTTPS connections.
8.
Does the firewall require a username and password to access the remote server?
9.
Do I require a proxy server to access the remote server?
10.
Is the proxy server port the default (1080) or another port (for example, 3128 for the Linux 
Squid proxy)?
11.
Does the firewall permit HTTPS connections initially or do I need to connect via HTTP 
first?
12.
Is the remote server configured to use SSL v3.0 or TLS 1.0? 
TLS1.0 is recommended, but SSL v3.0 is also supported. Versions prior to SSL v3.0 and 
later than TLS v1.0 are not currently supported.
13.
Are the Zebra Certificate Authority Certificates correctly installed on the remote server?
14.
Was the server’s certificate issued by Zebra and is it signed by the Zebra Certificate 
Authority?
15.
Has the server’s certificate expired?
16.
Is the printer’s date and time within the issue and expired period of the server’s certificate?
Note • 
If using the Linux Proxy Server Squid, and you are having trouble connecting, note 
that it may be configured to:
a.
disallow POST messages
b.
only operate in HTTP/1.0 mode 3
c.
disallow SSL connections.
Refer to your Linux Squid documentation for complete details.
