Azure Communications Service SMS SDK Issue

All of a sudden I've just started getting this error when i call the SMS communication service with this:

SmsSendResult sendResult = await client.SendAsync(object);

Haven't used it in a week or so, just updated the Nuget package which didn't appear to do anything.

{"Service request failed.\r\nStatus: 401 (Unauthorized)\r\n\r\nContent:\r\n{\"error\":{\"code\":\"Denied\",\"message\":\"Request was out of the allowed time difference.\"}}\r\n\r\nHeaders:\r\nTransfer-Encoding: chunked\r\nRequest-Context: REDACTED\r\nMS-CV: REDACTED\r\nX-Processing-Time: REDACTED\r\nX-Cache: REDACTED\r\nX-Azure-Ref: REDACTED\r\nDate: Fri, 03 Sep 2021 19:35:14 GMT\r\nContent-Type: application/json\r\n"}

I'm assuming something is going on with the service at this point.

Any insights are appreciated.

Thanks,
Jim

    Same issue with Australia Phone - 401 Unauthorized on attempt to send sms.

    Is there a solution or explanation? No clue what is going on. Email could be sent easily, but despite the acquired Australian Phone Number - 401 on SMS Send via SMS SDK

    Any update?

    Are you seeing this error in WSL?

    WSL has a known issue where the clock falls out of sync with the system clock and it can cause errors.

    https://github.com/microsoft/WSL/issues/10006

    I had a similar error when sending emails from WSL. Restarting WSL solved the problem.

    Close all wsl instances, then in powershell:

    wsl --shutdown

    And to restart:

    wsl
