 Troubleshooting connectivity issues

Here are basic trouble shooting steps to help you to fix some standard connectivity issues. 

Step 1: Verify that your firewall and/or web filtering application settings allow Reacts to connect, from your web browser window try to access

You should see the message: «{"Version":"","Body":"Echo OK!","Type":"System.String","Time":"2016-07-27T15:04:59.6325394Z","Id":"676b0cf1-e3ad-4cb7-bb9d-6076e2913efc"}».

Step 2: Ensure that there is no interference between your antivirus software and Reacts that could prevent the software from being launched.

Step 3: Enter your proxy information. If you connect though a proxy, you may need to manually enter the proxy information into the Reacts settings panel.
