Failed to call API to get access token

Hi Auth0 team and community,

We experienced failures to get SSO access token by using client credential grant every one week or two. The following is the exception. (We use dot net core 2.0.) Once it happens, almost all such calls failed.

Any help is highly appreciated!

fail: Microsoft.AspNetCore.Server.Kestrel[13]
Connection id “0HM831QDD5AOD”, Request id “0HM831QDD5AOD:00000001”: An unhandled exception was thrown by the application.
System.Net.Http.HttpRequestException: Error while copying content to a stream. —> System.IO.IOException: The write operation failed, see inner exception. —>
