Describe the bug

I am getting the error "could not start the proxy for the service".

All I did was add Aspire Orchestrator Support to my project. There is no conflict in the launchSettings.json, but I still get this error:

fail: Aspire.Hosting.Dcp.dcpctrl.ServiceReconciler[0]
could not start the proxy {"ServiceName": {"name":"servicea-http"}, "Reconciliation": 6, "error": "could not start the proxy for the service: listen tcp 127.0.0.1:5010: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted."}

Is that port in use?

@karolz-ms @dbreshears

[Aydinmfatih]

Here is my Service port : "applicationUrl": "https://localhost:7206;http://localhost:5010",

Aspire port : "applicationUrl": "https://localhost:17145;http://localhost:15184",

[davidfowl]

if you change the 5010 port does it work?

[Aydinmfatih]

Unfortunately, I have tried this before, but I keep getting the same error.

"could not start the proxy for the service: listen tcp 127.0.0.1:5025"

[davidfowl]

Does this help?

I checked the ports, but the ones I am using are not in use.

[davidfowl]

Can you try this #7317 (comment)

[Aydinmfatih]

I Tried for diffrent project and ı get System.IO.IOException: 'Failed to bind to address https://127.0.0.1:7094: address already in use.'

I tried #7317 (comment)

Are you using aspire 9.1? If not, try upgrading. 9.0 has known issues whereby if you restart your project, you'll see these errors as the new instance tries to use port before the old instance releases them.

[Aydinmfatih]

I was using Aspire 9 and updated to 9.1, but I'm still getting the same error:
System.IO.IOException: 'Failed to bind to address https://127.0.0.1:7094/: address already in use.'

@Aydinmfatih Can you share your project information? The csproj file of the app host and dotnet --info on the command line?

[dbreshears]

@Aydinmfatih, when this occurs, how many instances of dcp.exe or dcpctrl.exe are running?
