01Contact us
The fastest way to reach a human is email. Tell us what you were doing, what happened, and anything you’ve already tried. The more detail, the faster we can help.

02Quick fixes
Can’t connect to a host
Double-check the host address, port (SSH is usually 22), and username. Confirm the server is reachable from another SSH client on the same network, and that its firewall allows your connection. For key-based auth, make sure the matching public key is in the server’s ~/.ssh/authorized_keys.
“Host key changed” warning
Termite pins each server’s host key the first time you connect and warns if it later changes. This protects you from impersonation. If you genuinely rebuilt or migrated the server, remove the saved host and reconnect to trust the new key. If you didn’t change anything, stop and verify the server before continuing.
My session didn’t resume
Termite uses tmux on the server to keep sessions alive across reconnects. Make sure tmux is installed on the host (tmux -V). If a session won’t reattach, run tmux ls to see what’s running, or start fresh. Your previous session stays on the server until it ends.
I’m not getting finish notifications
Check that notifications are allowed for Termite in your device Settings, and that the feature is enabled in Termite’s settings for that host. Notifications require the app to have completed setup on the host at least once; reconnecting re-arms it.
The AI command composer says it’s unavailable
This is usually a temporary service hiccup. Try again in a moment. You can always type commands directly in the meantime. If it persists, let us know.
03Your data & privacy
Your SSH credentials are stored locally in your device’s Keychain and never leave the device. For the full details of what we collect, what we deliberately never touch, and how to request deletion, see our Privacy Policy.
04Feature requests & bugs
We read every message. If something’s broken or you have an idea that would make Termite better, email developer@sentrylinelabs.com with the details: a reproduction or screenshot for bugs, or a quick description of what you’re trying to do for feature requests.
