Problem with certificate in windows 2016

I have a problem. I installed the .NET application with a Windows 2008 R2 computer. If it works, I have communication, I configure it step by step and everything works correctly.
But there is another computer that contains Windows 2016 version .NET 22.8.0 compatible with 4.4.1.0, we have the same thing and it does not work, it sends a communication error and a certificate does not exist.

Has anyone happened to it?

Hi @Daniela de los Angeles.Salas Peña,

I found this older Community post that seems to be talking about a similar issue. Can you check it out and let me know if it helps - https://community.appdynamics.com/t5/Controller-SaaS-On-Premises/Net-Agent-install-fails-in-trial-SA...

Hi @Ryan.Paredez

It was not successful, I did the test and I get the same error, I share the evidence, 

Could you help me with more solutions please?

The certificate instance is installed in a proxy on a linux operating system
the certificate in linux asks me for a key
Here the issue is if you could provide me with some parameters to generate the key
or in your case the certificate where you could get it with the key if someone knows

Hi @Daniela de los Angeles.Salas Peña,

I found this info in an exiting support ticket. Please see if this info helps out. 

  • Can you please check whether you are able to access and browse the controller URL through Internet explorer on the agent machine where you are facing this issue? If the controller is not accessible using IE from the agent machine clearly states there is a network issue in your environment. 
    Please ask your network team needs to allow the traffic from the agent to the controller machine. 
    Once you are able to access the controller using IE the agent should also ideally work fine. 
  • Also, kindly open a command prompt as admin and use telnet command from server to controller at the specified port and verify if telnet is successful or not.
    telnet <controller> <port>
  • Also, can you please check to connect at non-ssl port and verify if it connects without any issue?


If telnet is not successful to the controller at the specific port from the server,  you would have to check and verify with your network team to open the port from server to controller.

telnet <controller> <port>

Once the port is open and you are able to telnet the controller at the specified port from the agent machine, then kindly test the connection through Agent configuration utility again and complete the configuration.


So the steps are:

  1. Please confirm if the controller host/port is accessible on the agent machine when opened in a browser. Run the appdynamics configuration wizard and make a test connection.


Also, I see you have a proxy involved. Is the proxy at network/system level or at the application level (in app.config/web.config) level? If so then we have to configure it in config.xml as below - 
<controller host="mycontroller.example.com">
  <application name="MyDotNetApplicaition" />
  <proxy host="myproxy.example.com" port="3128" enabled="true">
    <authentication enabled="true" user_name="MyProxyUser" password="password" domain="mydomain.com"/>
  </proxy>
</controller>

Hi @Ryan.Paredez 
That solution is already done.
What I was commenting on in the previous answer is the possibility of certificates, if they can provide a key or command to generate it

Please if you can help me

Hi @Daniela de los Angeles.Salas Peña,

Ah, sorry. I misread the last message. Did you get your install instructions from an AppD Docs page? If so, can you share that with me?

Hi @Ryan.Paredez 

I did not receive instructions as is, I only have a reference to this problem in this community forum
https://community.appdynamics.com/t5/Controller-SaaS-On-Premises/Net-Agent-install-fails-in-trial-SA...

What I require is that you provide me with the instance of the certificate is installed in a proxy in a linux operating system
the certificate in linux asks me for a key
Here the issue is if you could provide me with some parameters to generate the key
or in your case the certificate where you could get the key if someone knows
