There’s no indication of global problems with the current FBOS release, but there is a new port requirement (8883).
This sounds a lot like your schools network has port 8883 blocked.
Are you sure that was us and not some other device? We don’t use either of those.
Are you certain you weren’t reading old documentation for FBOS v12? The most recent port list can be found here. As mentioned, port 8883 is the new one that some schools have not added to the allow list yet.
I’m certain we will be able to fix the issue, but please do let me know if you’re still having trouble after enabling port 8883. We won’t support old versions after 60 days of a new release (the documentation explains why we don’t allow old versions on the official server).
If you are absolutely certain that you have port 8883 enabled and are still hitting issues, let me know and I can try to remote in to your device to see what is going on. Please provide your device ID if it gets to that point.
