Received this error from 10:30pm last night until 7:30am this morning. Across multiple devices. It started working 5 minutes ago.
Version 3.16.9.0
Wanted to post this anyway to get some feedback on what the issue was for future reference. This was also the first time I've googled an error message and not found any results so if this happens again to someone else hopefully this message and subsequent thread will provide some insight.
The message itself is pretty self-explanatory but after a few hours had gone by I grew concerned it was a generic message hiding some other issue.
