Signalr: "NetworkError: 500 Internal Server Error

[khcc]

When I am running the web site on my local computer it works properly, but when I uploading to my domain, its starts to generates this error. I am in rush, and it is very critical for me, I have done the whole project based on Signal and I m confused now, please please please help me soon.

500 means internal server error and you can get the actual error text from the event log, that'll help you diagnose the problem. If you're using ASP.NET you can turn custom errors off to get the actual error text in the network tab of your browser.

Dear David
The error was for Trust Level of my website which is fixed on Medium by my hosting company (Go Daddy). I asked them to change it they refused, I changed my hosting company to the one that has FULL level, it worked! And meantime, really, really Thank you for your great job! It is amazing and simple and light and lot of good things :)

[davidfowl]

Awesome!

I get this issue even with full trust? Is there another way to get around the /signalr/hubs 500 error?

[DamianEdwards]

Try debugging

[ChadWWatson]

Problem is this exist only on remote server. Locally works fine.

[ChadWWatson]

The 500 in fiddler is System.MissingMethodException: Method not found: 'System.Version System.Web.HttpRuntime.get_IISVersion()'.

You're running .net 4.5 locally and .net 4.0 on the remote server. You need to re-target your app to 4.0 in VS, uninstall and then install the SignalR package again (so you get the 4.0 version), then re-deploy.

Damian,
You are referring to VS2012 if I'm not mistaken. VS2010 doesn't show 4.5, just 4.0. When deploying project compiled on vs2010 to server that doesn't have 4.5, I get the same error.

I even had the same issue, I solved it by modifying a property of my class which was inheriting "Hub" Class.

myClass Properties --> Build Action --> Content.  (instead of "compile")

I hope this will help someone.

Hi,

Sorry, I have no idea about it.
Consider asking on https://jabbr.net/#/rooms/signalr where you can find the
developers of SignalR. (Assuming you didn't know about this).

Hello, I have same problem like the others... Same problem I have on two my applications on difference servers. Same is only implementation solution, what is ASP.Net MVC 3, C#. Both of my applications are running on "Full trust" prottection on IIS server. Locally it works fine but problems are on remote servers.

Applications are running fine, but returns there errors :( Here is screenshot from mozilla firebug/network.

Thanks for any Ideas!!!

It's August, 2017 and I have a GoDaddy account also. I have a very small sample app using SignalR which runs perfectly on localhost but will not run at my GoDaddy Site.
I have given full trust in web.config. I have set up virtual directories for signalr/hubs (in a vain hope that somehow the .NET generated hub would work). Nothing actually works and you always get the 500 internal server error.
Finally, I got a free account at smarterasp.net, dropped in the same code that is running on my localhost and it worked perfectly.
You can see the article I wrote and see the sample at SignalR - @ codeproject
