Hi scixing,
It sounds like you're having some trouble with deploying your Aspire application on Azure, especially with receiving 404 errors for all services except the dashboard. Here are a few troubleshooting steps you can take:
Dashboard Activation Delay: The Aspire dashboard can take up to 2 minutes to fully activate after deployment. If you try to access it (or other services) before it's ready, you may encounter a 404 error. Please try again after a short wait.
Missing or Incorrect Role Assignments: Ensure your account has the necessary Contributor or Owner role assigned to the Azure Container Apps environment. Without this, you may face access issues. You can verify this through the Azure Portal under Access control (IAM).
Correct Service URLs:The dashboard and services are hosted separately. Please make sure you're accessing the correct URL for each service. You can find the endpoint URLs in the Azure Portal under your Container App resources. Trying to access a service using the wrong route or dashboard URL will result in a 404.
Application Gateway / Hostname Redirect Issues (if applicable): If you're using Azure Application Gateway, make sure it’s not rewriting the hostname to *.azurewebsites.net. This mismatch can break routing and cause 404s.
Since you’re using Aspire, I recommend reviewing the official deployment documentation to ensure that you haven’t missed any specific requirements:
For your reference, please review the following documentations for further clarification:

Hello scixing,
Following up to see if you have chance to check my previous response and please let us know with an update to assist you further on this.
After my testing, I found that The deployment of NET Aspire Starter App is not a problem, but if Aspire is added when creating a blazor wep app project, the project cannot be accessed after deployment @Shireesha Eeraboina
I understand, it needs to be set to WithExternalHttpEndpoint
builder.AddProject<Projects.BlazorApp1>("blazorapp1")
.WithExternalHttpEndpoints();
Hello scixing,
after setting WithExternalHttpEndpoint are you able to resolve your issue?
Hello scixing,
Glad to hear that your issue has been resolved. And sharing the information.
Hello scixing,
After set to WithExternalHttpEndpoint issue has been resolved.
Copy
builder.AddProject<Projects.BlazorApp1>("blazorapp1")
.WithExternalHttpEndpoints();
