my UTM v9 notification was working fine, my email is gmail.
Yesterday, I upgrade my internet service from comcast to at&t gbit fiber, then I connected UTM v9 to the new service, everything seems working fine, except I have no more email notification from UTM. Anybody has idea what should I check on that? many thanks.
Good catch, Ting. I was going to ask if this was a home-use situation because AT&T blocks some ports on residential connections.
