I have an isy99 system, and have it set up for internet access. Self-signed certificate. Current software. After I leave my house, the internet access works for a few weeks, and then hangs. No response from the https: address. Tried several computers. This has happened every time, although the delay seems variable. I know the system is working, and the internet up, because it is still sending me temperature alerts from my system. Any ideas?
