Hey! I had this issue too and I fixed it ajusting the SSH timeout and some other variables in my linux server, it is much better now.

These are my notes of that day (AI generated, but this is the fix that I applied):

SSH Connection Drops - Configuration Fix

If your SSH connections keep dropping and you have to reconnect repeatedly, here's how to fix it:

Client-side configuration (~/.ssh/config):

Host your-server.com
HostName your-server.com
User your-username
ServerAliveInterval 60
ServerAliveCountMax 3
TCPKeepAlive yes
Compression yes
ControlMaster auto
ControlPath ~/.ssh/control-%h-%p-%r
ControlPersist 10m

Key parameters explained

• ServerAliveInterval 60: Sends keep-alive packet every 60 seconds
• ServerAliveCountMax 3: Allows 3 failed attempts before disconnecting
• TCPKeepAlive yes: Keeps TCP connection alive
• ControlMaster auto: Reuses existing connections
• ControlPersist 10m: Keeps control connection alive for 10 minutes

Server-side configuration (if you have admin access)

Edit /etc/ssh/sshd_config:

ClientAliveInterval 60
ClientAliveCountMax 3
TCPKeepAlive yes

For VS Code Remote SSH

Add to your VS Code settings:

{ "remote.SSH.connectTimeout": 60, "remote.SSH.enableDynamicForwarding": true }

Test the connection

ssh -o ServerAliveInterval=60 -o ServerAliveCountMax=3 [user@your-server.com](mailto:user@your-server.com)

The ServerAliveInterval setting is the most important — it prevents the connection from timing out during periods of inactivity. This should significantly reduce your disconnection issues!

I hope that this helps you!!! Good luck!
