trendline created 8 years ago

I am using aspnetzero version 2.2.0, the chat message feature which provided by SignalR, it works fine when debugging in visual studio on local machine. But after deployed the site to server, it returns 500 internal server error via below request URL:http://www.mysite.com/signalr/negotiate?clientProtocol=1.5&connectionData=%5B%7B%22name%22%3A%22abpcommonhub%22%7D%2C%7B%22name%22%3A%22chathub%22%7D%5D&_=1483523711860

Hi,

Probably this is the same problems with yours #1891@536442f0-c222-4a71-9068-b8964aa3c0fa. Can you check that ?

Thanks.

I already checked the post, I am not using Azure, I am using my own server.

Hi,

You can see the example here <a class="postlink" href="https://github.com/SignalR/SignalR/issues/3670#issuecomment-204041898">https://github.com/SignalR/SignalR/issu ... -204041898</a>. You can create this class in your web project. Then you will need to use it like this.

app.SetDataProtectionProvider(new YourCustomProtectionProvider());

By the way, do you have any error message in your Logs.txt file ?

Yes, some error in logs, this maybe related with SignalR

And, I am using asp.net core Zero, it seems in the StartUp.cs no extensions like app.SetDataProtectionProvider(), like below:

app.UseAbp(); app.MapSignalR();

Hi,

Do you have access to IIS on your hosting ? If so, in your application pool's advanced settings you can set Load User Profile to true and that might solve this problem.

Great! After set load user profile to true resolved the issue. Thanks a lot.

I have same problem. I am using aspnetZero v4.3.0.0 Asp.net Core targeting .net framework 4.6.1 + jquery. My test environment is Windows Server 2012 R2, IIS 8. I have made configurations as in "https://docs.microsoft.com/en-us/aspnet/core/publishing/iis?tabs=aspnetcore2x". I have also installed Websocket role for win server 2012. I googled so much but couldn't get any result. I also applied "https://github.com/aspnetzero/aspnet-zero-core/commit/8d88cdd6a27a03e9eb784bb7425ee38f58d1ba11" but no result.

I am getting "negotiate?clientProtocol=1.5&connectionData=%5B%7B%22name%22%3A%22abpcommonhub%22%7D%2C%7B%22name%22%3A%22chathub%22%7D%5D&_=1507899535628" 500 Internal Server Error.

Am I missing server configuration?

Looking forward for your reply!

Hi @goldstone,

Do you have any error message in Logs.txt under your web project ? There are different reasons of signalr problem.

I got the SignalR error mentioned when I did a clean install. After I created a tenant and a user the error went away. Sounds to me that and empty result (user list) may have been the root cause. Figure I share that observation with you all.

Hi,

Prerequisites What is your product version? 11.3.0

What is your product type (Angular or MVC)? Angular

What is product framework type (.net framework or .net core)? .NET Core

We got the same error. In our scenario, we want to connect to the API with SignalR from a console application. We do not get any problems on local with Angular app and console app. When we deploy the API to IIS, we get the following error after run the Console App. Do you have a suggestion?

"AspNetCore.Server.IIS.Core.IISHttpServer - Connection ID "17582052955455006947", Request ID "8000a8e4-0002-f400-b63f-84710c7967bb": An unhandled exception was thrown by the application. System.FormatException: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters."

Thank you for your support.
