Authorization for Microsoft App ID failed with status code Unauthorized and reason phrase 'Unauthorized'

[sogeg]

Hello!

I use my bot to send proactive messages. To do this I save conversation info and I use connector.Conversations.SendToConversationAsync to send the proactive message when required.

Here is my code:

var userAccount = new ChannelAccount(name: skypeConversation.FromName, id: skypeConversation.FromId);
var botAccount = new ChannelAccount(name: skypeConversation.RecipientName, id: skypeConversation.RecipientId);

var connector = new ConnectorClient(new Uri(skypeConversation.ServiceUrl));
var conversationId = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount); 
IMessageActivity message = Activity.CreateMessageActivity();
message.From = botAccount;
message.Recipient = userAccount;
message.Conversation = new ConversationAccount(id: conversationId.Id);
message.Text = skypeText;
message.Locale = "en-Us";

await connector.Conversations.SendToConversationAsync((Activity)message);

At first the SendToConversationAsync works fine. But after about 20 hours (not sure about the exact time) I get:
Authorization for Microsoft App ID ### failed with status code Unauthorized and reason phrase 'Unauthorized'
Any ideas?Is there a time window?

Hello @nwhitmont thank you for your reply.
The Operating System is Windows 2012 R2,
SKD Platform C#, Version 3.5.5.0.

The Deployment Environment is Windows 2012 R2, IIS Server

Issue:
The issue is that I can send proactive message for only some hours after the message I receive from the user. After about 20H I get an Unauthorized exception. Am I doing something wrong, or is there a time window?

Step 1: I save conversation info after I receive a message from the user.

//[BotAuthentication] Decorates Class
public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{
      if (activity.Type == ActivityTypes.Message)
      {
             SkypeConversation skypeConversation = new SkypeConversation();
             skypeConversation.FromId = activity.From.Id;
             skypeConversation.FromName = activity.From.Name;
             skypeConversation.ConversationId = activity.Conversation.Id;
             skypeConversation.Exceptions = 0;
             skypeConversation.RecipientId = activity.Recipient.Id;
             skypeConversation.RecipientName = activity.Recipient.Name;
             skypeConversation.ServiceUrl = activity.ServiceUrl;
             //Entity Framework Save
            db.SkypeConversations.Add(skypeConversation);
            db.SaveChanges();
      }
}

Step 2: I use the SkypeConversation object to send a proactive message (bot triggered)

//[BotAuthentication] Decorates Class

public async Task SendMessage(SkypeConversation skypeConversation, String text, String locale = null)
        {
            try
            {
                String skypeText = text.Replace("\r\n", ", \n\n");

                var userAccount = new ChannelAccount(name: skypeConversation.FromName, id: skypeConversation.FromId);
                var botAccount = new ChannelAccount(name: skypeConversation.RecipientName, id: skypeConversation.RecipientId);

                var connector = new ConnectorClient(new Uri(skypeConversation.ServiceUrl));
                var conversationId = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount); 
                IMessageActivity message = Activity.CreateMessageActivity();
                message.From = botAccount;
                message.Recipient = userAccount;
                message.Conversation = new ConversationAccount(id: conversationId.Id);
                message.Text = skypeText;
                message.ChannelId = "skype";
                if (locale == null)
                    message.Locale = "en-Us";
                else
                    message.Locale = locale;

                await connector.Conversations.SendToConversationAsync((Activity)message);
            }
            catch(Exception ex)
            {
            }
       }

In the first hours everything works fine. However after about 20H I get the following exception:

System.UnauthorizedAccessException: Authorization for Microsoft App ID 344dd93f-9056-4b47-9f21-28704ffabb87 failed with status code Unauthorized and reason phrase 'Unauthorized' ---> System.Net.Http.HttpRequestException: Response status code does not indicate success: 401 (Unauthorized). at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode() at Microsoft.Bot.Connector.JwtTokenRefresher.d__2.MoveNext() --- End of inner exception stack trace --- at Microsoft.Bot.Connector.JwtTokenRefresher.d__2.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd(Task task) at Microsoft.Bot.Connector.Conversations.d__5.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Bot.Connector.ConversationsExtensions.d__17.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at EscapeAll.Skype.Utilities.d__0.MoveNext() in C:\Users\G\Documents\Visual Studio 2015\Projects\Esc\XXXX\Skype\Utilities.cs:line 25

What I expected was to continue to send messages as in the first 20Hours.

Thank you for your help :)

Maybe I need offline_access scope? I noticed that when I send a message to the skype account, everything works again

[ZOXEXIVO]

Proactively messages from another server is big problem

[JasonSowers]

@sogeg are you still having this problem in the newest version of the SDK 3.8.1 at the time of writing this?

[mayankthebest]

I am also having the same problem. I am on version 3.8.1 of the SDK.

[phaetto]

I can repro the same behavior in the above case plus after every deploy (or restart) of my web application - I am on version 3.8.1 as well.

[EricDahlvang]

You need to add a call to
MicrosoftAppCredentials.TrustServiceUrl(serviceUrl);
This is done automatically when you are replying to a message, but not when using the ConnectorClient

[sogeg]

@EricDahlvang Thanks!
MicrosoftAppCredentials.TrustServiceUrl(serviceUrl);
That seems to work. I have no issue after 48 hours after the first message.

[sakshisa27]

Hi I am having the same problem. I have already used MicrosoftAppCredentials.TrustServiceUrl(serviceUrl);
It was working fine but after 7 hours it starts giving the same error

[EricDahlvang]

@sakshisa27 Please open a new issue, describing your problem in detail. This issue is closed.

[alexdrenea]

MicrosoftAppCredentials.TrustServiceUrl(serviceUrl); did it for me
This needs to be documented somewhere since this is the first and only place I saw this info.
"Only" took me a few hours to find it... i'm sure others will struggle too.

[farrukhpisces]

MicrosoftAppCredentials.TrustServiceUrl(serviceUrl);
This also works for me as i was trying send message from my application to bot.
Thanks :)
