Other Typical Errors

While SSL/TLS connection errors are the most common, there are issues that can arise that prevent a successful connection. This section highlights the most common issues.

Error

Cause / Solution

 

 

"Read failed with an unexpected

This message typically indicates that connection to the remote

error"

server was lost. The connection can either be lost due to the

 

server powering off or resetting, the firewall or proxy server

 

shutting down the connection, or because the remote server

 

gracefully requests that the connection be discontinued.

 

Note • After 60 seconds of inactivity on the connection

 

the printer will attempt to contact the server via a TCP

 

Keepalive. If the connection is still present the server

 

will respond and the connection will remain open. After

 

10 successive failed attempts to contact the remote the

 

printer will assume the connection is severed and close

 

the connection. The printer will resume it's attempt to

 

connect to the remote server so that when the server

 

comes back online the printer will re-establish

 

communication.

 

 

"Failed to connect (SP = #, CI = #,

If this error is seen one or more of the ‘#’ values will be set to 0.

UW = #, AC = #, PC = #)"

This is an indication of an incorrect configuration of the remote

 

server. Ensure that the remote server is setup according to the

 

Servlet configuration in the Zebra Link-OS SDK

 

documentation.

 

This typically indicates an incorrect version of the remote

 

Application Server (for example, Apache/Tomcat version may

 

be incorrect). If this issue persists contact Zebra Technical

 

Support.
