Went to use my HM 4.3 the other day and noticed the ambient temp was way off. It was reading 400F outside of the pit. I bought a couple new probes and the issue persist. I also noticed that the IP address the HM shows on start up is no longer pulling up anything on my browser. Any ideas what could be wrong and how to solve it? Went to the website today and saw the store was closing and everything is sold out. I hope it's not a hardware issue and I'm SOL, as I really love this device.
