[Bug]: Websocket 404 in Firefox about cognitive-services-speech-sdk-js

[magic-maker]

I have encountered the same issue. This arises because the latest version of Firefox (124) has enabled the HTTP2 protocol by default for WebSocket connections. This change leads to a failure when connecting to the Azure Cognitive Service API, resulting in a 404 error as the servers are unable to process the request properly. The connection does not successfully upgrade to a WebSocket connection.

To test this, ensure that the parameter 'network.http.http2.websockets' is set to 'true' in about:config. This is the new default setting which is causing the issue. It's important to note that previously installed versions of Firefox retain this setting as 'false', even after updates.

For your information, this issue does not occur on Chrome on the same machine; it is specific to Firefox and is not related to subscription, authentication, or similar factors.

Thank you @magic-maker that solves my issue with Firefox. Perhaps I'm having a different problem with Safari.

I'm guessing Azure will have to make a change to support this new behavior?

Yes, I will let the service team know, and, if corrective actions aren't taken, open an IcM.

@magic-maker, thank you for relaying that information!

Update: The service team is currently testing a fix, approval and deployment are TBD, but probably by end of April at latest.

@claptimes5 Thank you for using the JS Speech SDK, and writing this issue up. I just tested the sample on FF/win11 (westeurope) and Safari/macOS17.4.1 (westus2) with no issues. If you could add the following logging API call to your code and send a screenshot of the console output, that could help with understanding why this is happening for you:

sdk.Diagnostics.SetLoggingLevel(sdk.LogLevel.Debug);

[claptimes5]

Thanks for the fast response! Here is my output:

@claptimes5 Status code 1006 is almost always an auth/keys issue. Could you create a new subscription key and see if that works?

[claptimes5]

Thanks. I tested using eastus and get the same error.

[claptimes5]

And to make sure, I used the new key/region in Chrome and have no problem.

This issue also just started happening for me a day or two ago with Firefox (124.2.0) on Android (Pixel 6 Pro).

I tested it with SDK versions 1.32.0 and 1.36.0 and it happens with both.

I made no changes to my code prior to the issue and it works in Chrome on Android (I haven't tested in Safari).
