If your radar agent is unable to communicate with BlazeMeter/Runscope, here are a couple of steps you can take to solve this issue:

• Make sure that you are running the latest version of the agent. You can check your agent version by running it with the --version flag. You can download the latest version here.
• Run a ping and curl request on the same machine that the agent is running on, and check that you receive a valid response.
  For example:

  • ping -c 5 api.runscope.com

  • curl https://api.runscope.com

• Run the agent with the --verbose flag to get a more detailed output, and check for any error messages.
• Check your server's proxy settings to see if it's not blocking any requests to api.runscope.com. For more information on using the agent with a proxy, check the HTTP/HTTPS Proxy Setup article.
• If the server is successfully communicating with Runscope, and you have checked your proxy settings, check that your API test's environment is not misconfigured to use a disconnected remote agent with the same name.
