Java.net.SocketTimeoutException: Read timed out signifies that the client was not able to read any data from the server within the specified timeout period. This may occur due to a variety of reasons, including slow network or server response, network congestion, or firewall issues. If tcpdump is not showing any activity, it suggests that the network traffic is not reaching the client or server. This may be caused by routing issues, network outages, or other similar problems. You may need to investigate further to determine the root cause of the issue.
