ssh ubuntu networking bash

After trying multiple solutions online, I still can't figure this out. I'm experiencing a frustrating scenario where my SSH connection to a remote server drops intermittently, and I see the behavior message `ClientLoopSend() send packet: Network is unreachable`. This happens despite the fact that my internet connection seems stable. I checked the SSH configuration, and my `/etc/ssh/sshd_config` has `ClientAliveInterval 60` and `ClientAliveCountMax 3`, which should keep the connection alive. I've tried increasing the timeout values to see if it has any impact, but the scenario continues. Additionally, I have tested the connection with `ping` to the server's IP address, and there are no noticeable packet losses, which makes me think it could be something specific with the SSH configuration or network settings. To rule out any DNS issues, I can also SSH directly using the IP address instead of the hostname, but the question still occurs. I would appreciate any insights on what additional configurations or troubleshooting steps I might be missing here. Here's the relevant part of my `sshd_config`: ```bash # /etc/ssh/sshd_config ClientAliveInterval 60 ClientAliveCountMax 3 TCPKeepAlive yes Port 22 ``` And my local SSH command looks like this: ```bash ssh -v user@hostname ``` I've also ensured that my local firewall settings are allowing outbound SSH traffic. Any help in diagnosing why the connection keeps dropping would be greatly appreciated! My development environment is Ubuntu. Thanks in advance! Has anyone dealt with something similar?
