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 
error"
This message typically indicates that connection to the remote 
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 = #, 
UW = #, AC = #, PC = #)"
If this error is seen one or more of the ‘#’ values will be set to 0. 
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.
