"No SSH agent is running"
Start the OpenSSH Authentication Agent service (Services → OpenSSH Authentication Agent → Automatic), add your key with ssh-add, or choose Key file instead.
"Port already in use"
Another program (often a local database) listens on that port. Pick another local port, for example 15432 instead of 5432.
What is a jump host?
A server you connect through to reach another one (ProxyJump). Write it as user@bastion:22; several are separated by commas.
The server key changed
This happens when a server is reinstalled, but it can also mean someone is in the middle. Check with whoever runs the server; then remove the old line for it from your known_hosts and connect again.
Does it start with Windows?
Settings → Start when I sign in. With Pro, tunnels marked "Open when the app starts" come up on their own.
