neilenns commented 1 year ago

This is happing to a fellow controller. On launch of vATIS he gets the "checking for new navigation data" message and then the app crashes:

System.Threading.Tasks.TaskCanceledException: A task was canceled.
   at System.Threading.Tasks.TaskCompletionSourceWithCancellation`1.WaitWithCancellationAsync(CancellationToken cancellationToken)
   at System.Net.Http.HttpConnectionPool.GetHttp11ConnectionAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken)

We've tried uninstalling and nuking the vATIS-4.0 folder from %localappdata% on his machine then reinstalling beta 12 but the exception still happens.

Is that the entirety of the exception stack trace?

I believe so. Let me ask him

He says yes, the rest was just version info for the assemblies, but will get me the entire thing in a day or two (he's away from his computer for the next few days).

In beta 13, the HttpClient is forced to use IPv4, which will hopefully fix this issue.

I'm theorizing that the user is getting the TaskCanceledException because the http request is timing out. I recall some vPilot users getting a similar error when the new http auth method was introduced; restarting the computer or router was a temporary solution for some users. The solution that was implemented in vPilot was to make the http request to the auth token endpoint using the IPv4 address.

I let him know. He likely won't be able to try it for another day or so, but I'll report back once I hear results.

Seems like that change fixed it:

Happy to report vATIS seems to work fine with beta 13!
