We are using Microsoft.AspNet.SignalR Version=2.1.1.0 running on Windows Server 2016, IIS 10.
We see the following errors in the server logs -
SignalR.Transports.WebSocketTransport Error: 0 : OnError(1531b342-8587-4082-a027-b57505e29a8d, System.Net.WebSockets.WebSocketException (0x80070026): Reached the end of the file
at System.Web.WebSockets.WebSocketPipe.<>c__DisplayClass9_0.b__0(Int32 hrError, Int32 cbIO, Boolean fUtf8Encoded, Boolean fFinalFragment, Boolean fClose)
What could be the cause of above error?

We have two dotnet applications that publish and subscribe to RabbitMQ respectively. Our developers tested it locally and they work fine on their workstation (launch through Visual Studio). However, when we build them into container and run them, RabbitMQ logs will show the following error messages:
2022-11-01 09:29:15.998692+00:00 [info] <0.1560.868> accepting AMQP connection <0.1560.868>

2022-11-01 09:31:22.599983+00:00 [error] <0.2112.868> {handshake_timeout,frame_header}
And below is the error message on our dotnet container:

I have spent two days googling and troubleshooting but I am not a developer myself and couldn't find anything similar to our issue. Any help and guidance would be appreciated.
RabbitMQ version: 3.10.5
Erlang version: 24.3.4
.NET version: 6.0.10
RabbitMQ Client Library version: 6.2.1
Unhandled exception. System.Data.SqlClient.SqlException (0x80131904): A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - Success)
This is a NET5.0 console app using dapper to execute a stored procedure that will not store a result. The app is running from a linux docker container (Docker Desktop - Windows). The error happens each time a new container is created, and run for this first time. If the container is run again, the error will not occur.
using(IDbConnection sc = new SqlConnection("Server=my-azure-managed-instance.database.windows.net;Database=MyDB;User Id=me;Password=pw;")
{
sc.Execute("usp_MyProcedure", commandType: CommandType.StoredProcedure);
}
Does anyone know what situations might end up with "(provider: TCP Provider, error: 0 - Success)" as an error message?
I have a misbehaving 3rd party ASP.NET application that is causing IIS to crash. I can't understand how application that throws a simple, unhandled primary key exception is a sufficient reason to kill the web server process.
I was under the mistaken impression that putting a site in it's own application pool would somehow insulate other sites on the web server from errant behavior. I understand that maybe an application that had run-away resource consumption might kill the entire process, but I don't understand how one vendor's unhandled application exception can be allowed to negatively affect every other site on the web server.
I did some web searches and saw that this may happen if a site repeatedly has issues (default setting 5 times in 5 minutes) but that's not what's happening here. What's happening here is every time this exception happens, which is about once every 3 or 4 days, the whole IIS process aborts and causes a momentary outage of ALL of my sites on this web server.
I may possibly have some obscure setting misconfigured. For the most part, my IIS sites and application pools are configured with default settings and these servers have been up and running for years before this issue started occurring in September.
Any thoughts would be greatly appreciated.
System Particulars:
Windows 2008 R2
IIS 7.5

Here are parts of the 3 event entries that happen every time this issue occurs:

Seems the expected behaviour for unhandled exceptions occuring outside of the request context is to terminate the worker process. So if your third party app is doing some async work for example, and throws an unhandled exception, this will meet the criteria. See https://support.microsoft.com/en-us/kb/911816

I have many server 2012 (IIS 8) that I administer and ALL of them are having this problem starting within 48 hours of installing Microsoft updates this month. I checked my application logs over two years and this error had never existed before this month and the only delta in the environment was January's patches!
It is not IIS error. It seems it is a bad request or something else.
The clue is in :"StackTrace: at System.Data.SqlClient.SqlConnection.OnError"
I am not a programmer and unfortunately the programmers that have tried to help me could not. I connected my Woocommerce site successfully to Quickbooks using Webconnector initially. An unknown event caused us to receive this error, and since then webconnector has not been able to connect. I uninstalled then reinstalled the plugin and webconnector, and deleted all the old files on the database. Then it seemed to work for a split second, then produced the same error. The programmer suggested that it is because my main website is http not https. The shopping cart and admin pages are set to https.
Any help is greatly appreciated!

Your programmer already answered your question:
The programmer suggested that it is because my main website is http not https.
If you visit the URL:
https://www.farmacisthealing.com/?qbconnector=4Ty8Curko000
You'll see you get bounced to a non-HTTPS URL immediately. That shouldn't be happening. Either your website is configured wrong and redirecting you, or your web host/web server is configured wrong and redirecting you.

I used Web Deploy on the server to create the settings file using IIS on the host. This error appears during the simple web page compatibility test. Any clues as to what may be going on?
The error is basically because the remote server, or the hosting service provider closed the request.
Sometimes it is also stated as the server is trying to deny or is try to cancel the requests. For instance, a user started to download some file or a page, and the server is off so the download would be cancelled, or the download would fail.
There are many issues for this error code.
Here is a post from another forum. forums.asp.net
The best method would be to check the settings on the server that you are having hosting from. Or contact them directly to get help regarding this issue.
Edit:
Getting LogFiles:
You can get the LogFiles here:

HttpRunTime:
Secondly the request closed issue can also raise if the httpRunTime is out (timeout). But that exception isn't here I am sure, however still try this too: http://msdn.microsoft.com/en-us/library/e1f13641.aspx
Antivirus (If any):
Also, please try check if Antivirus is installed, then is it allowing the server to communicate with users or not? Sometimes along with Firewall, Antivirus might also try to stop the connections.
I recently had the exact same eventLogs, after the webmatrix web deploy throwed a "can not publish" (without any apparent reasons because it worked several month so far).
After some searches (unlucky) and a lot of fumbling, I got it to work again just by using a windows user with administrator privileges instead of the IIS Manager Users configuration.
