Device no longer reporting and not accessible in IDE

I’ve been messing around with the Google Sheets Logging SmartApp and noticed one of my open/close sensors has stopped reporting it’s temperature changes. I’m not at home so I can’t test to see if it’s reporting open/close events either. When I look at the device in the ST App it shows that the temp has changed and I can refresh the device but no status shows in the Live Log and no event is called for SmartApps to pick up on. When I decided to check the device in IDE I was greeted by the following error:

I confirmed that I was able to get into my other devices just fine using IDE.

Any ideas what’s going on here? Is it just another instance of server-side issues?
