unexpectedly failed to authorize

Hi appauth-team,

Iam totally confused and unfortunately can't help myself. Hope you guy's have the right questions to fix my issue.

Since yesterday my openid-connect implementation to keycloak fails. Everything worked nicely until last week. The problem is, I don't exactly know what i did changed. However, I'm sure updated Flutter, but I think authorization did worked afterwards. Furthermore I didn't touch the auth-implementation.

Postman tests with the same config-params are still working. I checked the android- and ios-setup, but everything is like in the flutter_appauth-readme.md. I also have done that flutter clean stuff, you sometimes have to do, but without any success.

The Stacktrace is the following (in android-simulator and ios-simulator):

[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(authorize_and_exchange_code_failed, Failed to authorize: Issued at time is more than 600 seconds before or after the current time, null, null)
#0      StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:653:7)
#1      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:296:18)<asynchronous suspension>

<asynchronous suspension>
#3      AppAuthApiImpl.login (package:appauthtest/app_auth_auth_api.dart:50:20)
<asynchronous suspension>

The failing line is:

final result = await _appAuth.authorizeAndExchangeCode(
      AuthorizationTokenRequest(CLIENT_ID, REDIRECT_URI,
          issuer: ISSUER,
          scopes: ['openid'],
          preferEphemeralSession: true),
    );
