Diagnose before guessing
Host troubleshooting
A structured path for connection, startup, performance, and update problems.
Check in order
- Confirm the service process is running and its logs show a clean startup.
- Confirm the endpoint and required ports are reachable from outside the host network.
- Compare client and server versions and compatibility requirements.
- Check resource pressure, firewall rules, and recent changes.
- Reproduce with a minimal configuration before changing several things at once.
When the issue persists
Record the version, operating system, endpoint symptoms, relevant logs, and the last known working change before asking for help.
