The second problem was an SSL certificate that didn't get renewed in time. Automated things sometimes break when other companies change things. It's fixed too now.
Hi,
We can get your agent/s back up within a few minutes. Please see this post.

Now it is ok
It seems that the NTP was not working correctly on your device but I need more time to evaluate all the things I have been testing.
The HW agent is now with the latest firmware which I know is stable.
Sorry again for the misunderstanding
