Hi expert,

  We use telnet server version 7.0 path 9. We have found a problem where the device can connect to the TELNET SERVER for a while. Then, occasionally, all devices are unable to connect to the TELNET SERVER. When the problem occurs, we just need to reopen the TELNET SERVER CONFIGURA icon on the server desktop, and the service returns to normal. We don’t know what caused this problem. Please help, thank you.
