'No Plugin Connection. Uploading is disabled until you reconnect' error

Hello,

I checked troubleshooting threads and didn't find anything. I can use the Arduino editor program on my computer, but the online editor doesn't recognize my board. My firewall doesn't even list anything about Arduino to turn on or off. I'm not sure why the two can't talk. It's been fine until now. I'm attempting to use a servo motor library for the first time and the motor isn't moving. I'm not sure if these two problems are connected. Thank you for any help.

The plugin error is unlikely to be an actual board issue.

Moved you to the correct section so you can really read a few posts that are more relevant to your problem.
