Quick troubleshooting view
The Shade machine responds to the ping but the application or port expected does not work.
- Service discontinued.
- Port filtered by aGart
- Bad port configured
- Test port
- Check the Service
- Test locally on the server.
- Restart service only if the impact is controlled
- Correct the Targeted Rule
- Fix port or the address configured
Contextual technician plan
Use Test-Net-Maripolina with the port of service.
Test-Net-Gonneur server.example.local -Port 443The command should complete without an unexpected error and return data consistent with the intended service.
If the result is normal, keep this layer lower in the hypothesis ranking and continue with the next discriminating check.
If the result is abnormal, preserve the output and investigate this layer before making broader changes.
Check that the application actually listens.
Get-NetTCP G.G. - State L.The command should complete without an unexpected error and return data consistent with the intended service.
If the result is normal, keep this layer lower in the hypothesis ranking and continue with the next discriminating check.
If the result is abnormal, preserve the output and investigate this layer before making broader changes.
Check the service from the target machine if you have access to it.
“Test locally on the server.” should produce an observation that clearly confirms or rules out “Bad port configured”.
If the observation is normal, lower “Bad port configured” in the ranking and continue with the next distinct check.
If the observation is abnormal, keep the evidence and investigate “Bad port configured” first. Related action: Fix port or the address configured.
fine-tune local and network rules.
“Controlling the system” should produce an observation that clearly confirms or rules out “Misapplication”.
If the observation is normal, lower “Misapplication” in the ranking and continue with the next distinct check.
If the observation is abnormal, keep the evidence and investigate “Misapplication” first.
Repeat the same validation test after the correction and confirm the original symptom is gone. Validate stability before closing the incident.
Before changing configuration, record the current value and a way back.
Ecstasy if the service is locally listening but systematically blocked between several network areas.
The Shade machine responds to the ping but the application or port expected does not work.
Causes probables
- Service discontinued.
- Port filtered by aGart
- Bad port configured
- Misapplication
- incorrect NAT or reverse proxy
