arterySignalR/ping MVC4 was not found

Question

I'm using MVC4, C#, Entity framework with repository pattern and I installed the Elmah nuget package. I have set the Elmah to send email when application error appear and since that I receive this:

System.Web.HttpException: The controller for path '/3582be999d2646eca85b82b5302fc0af/arterySignalR/ping' was not found or does not implement IController.

I dont know why I receive that error, I even don't know what arterySignalR/ping is and I want to know if someone of you know the solution to solve that.

Thank you very much,

Answer 1

That is a 404 Error that has been picked up by ELMAH. Someone requested that url from your website but as it does not exist it generated the 404 error.

If you do not know what arterySignalR/ping is, then you can simply ignore it. It could be simple as someone mistyping the website url. If the error is repeating continuously, then it could indicate a problem with a script/webpage or another application which may warrant attention.
