Usually, this prompt appears because manual authentication is used when initiating the connection, and the controlled side does not confirm it in time. However, the current connection is password-authenticated, so the above reasons can be ruled out. The remaining is that the network latency from the control end or the controlled end to the control server is relatively large.

However, if you are still not sure that there is no corresponding cause, you can use Unicorn Network Analyzer to further analyze the cause, start the analysis tool, and find that the packet capture is very slow to send data, and some even take two minutes to send a message packet, please see the following figure:

Conclusion
Finally, we found the reason, that is, because of network congestion, the sending of data is very slow, and the client times out.
