Error Message "Connection Error Box" or 15 Second Countdown Timer Logging in to Exercise Instance

If you go to “Join” or log in to your range exercise cloud instance and get a black screen with a “connection error box” pop up message or a countdown timer, this means that your exercise cloud instance was not ready for you to log in yet. The error message should look something like this:

The error message displays, "The target system is currently unreachable. You may be able to reconnect, or may need to return to the exercise area and power cycle your exercise. If this problem persists an Instructor or TA may need to reset the exercise".

Troubleshooting Steps

  1. If you are getting a 15 second countdown, first just wait for it to time out. Sometimes the range simply attempts to connect too quickly.

  2. If it continues to count down and time out, then make sure exercise is started by

    • navigating back to the course page,

    • hitting CTRL-SHIFT-R to do a forced refresh,

    • clicking start and/or join again

  3. Wait for the next connection attempt to succeed (up to three times)

If you continue to experience the error, we recommend restarting or resetting the Virtual Machine. You can follow this process in our article, How to Restart and Reset a Virtual Machine.

If you continue to experience the error message after resetting your Virtual Machine, please Submit a Support Ticket. Please indicate the course, exercise, and user who is running into this error.
