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 |
| 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 |
| 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. |
