The remote name could not be resolved

Hi Team,


I have installed the .net agent on the windows server and it shows waiting for a connection. When I checked in AgentLog it shows the below error, please help how to fix this issue.

Thank you for posting a question on the community!


First of all, I recommend checking your network between a controller and the windows server.
By executing nslookup command on the windows server, you can make sure if the controller host name cam be resolved correctly.
nslookup <Your Controller Name>
If it fails, there might be some problems on the network.
And if a proxy server exists between the controller and the windows server, you also need to configure proxy settings.
The document link to proxy configuration:
Please let us know if you have any questions.
