Azure Blazor WASM not loading on some browsers/device dll files NS_ERROR_NET_PARTIAL_TRANSFER

Kevin Redfern 20 Reputation points

I am experiencing an issue with a custom domain against a Wep App on azure.

The url works fine,

The custom domain associated with that doesn't want to load.

This is the type of error I am getting with firefox.

This error has happened before, but just went away. Last time I thought it was a dns issues or caching with service providers as in the area we did have outages.

The website itself has api's on it, and they are all functioning ok. But it will not serve the frontend, which is blazor wasm .net6

I can't seem to prove or disprove what might be the underlying issue.

Any help or pointers would be massively appreciated.

    @Kevin Redfern Thanks for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.

    Based on the information shared, I have understood that you request to your Blazor is failing and you are seeing this error NS_ERROR_NET_PARTIAL_TRANSFER message in the browser network trace and also you have mentioned that issue is self-resolved.

    When I have researched about the error message all are pointing and this might be related to DNS issue. As you have mentioned that your webapp is configured with custom domain.

    Could you please run the Binding & SSL configuration Detector in SSL and Domain category under Diagnose and Solve Problems of your webapp to check and eliminate whether are they any configuration issue.
