EnvisaLink try to connect externally without permission

Post by pos42 »

Hi

I have had the Envisalink card connected to eye-zone earlier. Now I have removed my account due to that I want to run it all local. But in my FW I can see that the EnvisaLink tries to connect externally over and over again to 198.61.170.85, so I had to block the outgoing traffic in my firewall. The card is very aggressive in its try to connect.... And this goes on forever.

WHY do this happen? What do I do to make it stop?

Because it is a cloud-connected device. It is doing what it is supposed to do.

If you just let module connect normally it would be told that you don't have a cloud account and it will stop trying to "call home" so often.

Thanks for the info

Will in auto update firmware and then reboot if it finds a new one, even though I have no account active at eye-zon?

Nope. By not having an Envisalerts account you are saying you want nothing to do with the online services and we respect that.
