Windows 10: Intermittent requests returns "http error 500.0 - ancm in-process handler load failure"....

We had a service with 2.2 with few REST endpoints. We upgraded the framework to 3.3. Deployed the same in on-prem IIS 6.0. Everything works fine with Swagger. But on calling the same endpoint with multiple threads using JMETER with 5 user calls at a time. we are getting response HTTP Error 500.0 - ANCM In-Process Handler Load Failure Common causes of this issue: The specified version of Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found. The in process request handler, Microsoft.AspNetCore.Server.IIS, was not referenced in the application. ANCM could not find dotnet. Trouble

Reviews page error

This happens only if you do not let the " auto suggestion search box" appear and hit enter right after finishing typing.

It seems that it is the result of an XML HTTP Request that has/returns status 0, because the page is "reloaded" before the request was able to be processed by the server.

 

Error: No work available to process

Hmm. Either it's put out errors and WCG is limiting the work units available, or the project list may not be set to supply other WU when one runs out. (if the problem lies here and not on your end)

On the options to your left, if you go into Results Status, select the computer from Device Name and then look through results see if either they were returned late, errors or any other kind of issue that would stop the servers supplying WU from that perspective.

If there are no errors then it's maybe down to your project list. So selecting Device Manager from the left menu and then clicking on the profile assigned to that computer and make sure that it's assigned to receive WU for other projects if they run out.

At least those steps will rule out problems from the WCG end.

 

HTTP Error 500 on Facebook

Hi,

Thanks for posting your query to Microsoft forum.

Is this issue confined with Facebook website?

The ‘’HTTP 500’’ error is an HTTP [Hyper Text Transfer Protocol] status code that means that the request you sent to the website server (i.e. a request to load a web page) was somehow malformed therefore the server was unable to understand or process
the request.

I would recommend you to add the website you are having issue to the trusted site list on Internet explorer and check if it helps. Here are the steps below to add the websites to the trusted site list.

• 
  Press Windows key + R and type inetcpl.cpl and hit
  enter.
  
• 
  Click on the Security Tab.
  
• 
  Select the Trusted Site option
  
• 
  Click on Sites. You can add the sites to the zone and all the websites in this zone will use the zone’s security settings.
  
• 
  Click on Apply and Ok.
