I’m starting to think it might be a hardware issue, since the issue is progressively worse. ---

I’m trying to figure out what’s going on here. Can you guys drop send me the Core id via a PM and make sure that the device is breathing cyan? Also, what colour are your cores? ---

Hey guys, Just wanting to pop by to ask if you guys did a **deep update** and resulted in this issue? ---

Hi, I just sent my core ID. Yes, I’ve done a deep update and cc3000 reflash trying to fix the issue, but there were problems before that. Eric ---

Hey @ebarendt, I’m working with @Dave as there’s similar issues on my side. If i have anything i’ll post here to update you guys. Once again, sorry for the issue. 😃 ---

Hey guys, the problem might be temporarily resolved now. Can you guys try it again? If your core enters **breathing cyan** but you can’t seem to reach it, drop @Dave a note with your core id. Thanks! ---

So my core finally started working today, Yay, then I took it to a buddies house and it stopped working again. Same place it stopped working last time it can’t be a coincidence. It was tied to my mobil hotspot, though It was working all day on hotspot. Well back to square 1 ---

Hey All I just wanted to pop in and say that I just deployed a fix a few minutes ago that I think will fix the “my core is breathing but the api thinks it’s offline” bug we had for some this week. My apologies again for that, but it should be fixed and happy again. I’ll keep monitoring things, but please feel free to ping us if anything else seems weird. 🙂 Thanks! David ---

Thank you Dave, Core is working fine again. I don’t think I will be taking it to my buddies house anymore though. [Previous page](https://community.particle.io/t/device-is-not-connected/7421.md?page=1)
